List three traits that you have: _________________________ _________________________ _________________________
Shnorfs
List traits that can vary between shnorfs: _________________________ _________________________ _________________________ _________________________ _________________________ _________________________
Circle the traits in question 4 that are the same in the siblings (generation 2).
What patterns can you identify in this set of offspring (generation 2)?_____________________ ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

A model is your understanding of how traits are inherited. What key points need to be included in a model of heredity?
There are __________________________ in a population of one species.
Siblings have traits that are ___________________________________________________ but they have more traits ______________________________ with each other than with the general population.
In general, family members are not _______________________ to each other.
As a class we chose to look at the: Parent Offspring
What patterns do you notice about generation ______ of shnorfs compared to generation 2?_____________________________________________________________________________ ______________________________________________________________________________________________________________________________________________________________
What additional key points need to be included in a model of heredity?
Parents have traits that are ___________________________________________________ from their offspring, but they have more traits ______________________________ with each other than with the general population.
Use the information from questions 7 and 10 to create your initial model of heredity (a poster which explains how traits are inherited).
Based on your model, describe what you think another species of sibling monsters would look like.___________________________________________________________________________ _______________________________________________________________________________

Part 2: Multigenerational Observations—Dromos
Dromos
List traits that can vary between dromos: _________________________ _________________________ _________________________ _________________________ _________________________ _________________________
Does your prediction match with the dromo siblings? Yes No
What patterns can you identify about the offspring (generation 2) in family 1?________________ _______________________________________________________________________________
What patterns can you identify about the offspring (generation 2) in family 2?________________ _______________________________________________________________________________
What patterns can you identify between family 1 and family 2?____________________________ ______________________________________________________________________________________________________________________________________________________________
What do you think caused the families to look the way they do?___________________________ _______________________________________________________________________________
What additional key points need to be included in a model of heredity?
Some species produce offspring siblings that are __________________________________
As a class we chose to look at the: Parent Offspring
What patterns do you notice about generation ______ of dromos compared to generation 2? ______________________________________________________________________________________________________________________________________________________________

What was different about shnorfs and dromos? ________________________________________ ______________________________________________________________________________________________________________________________________________________________
What additional key points need to be included in a model of heredity?
Some species have parents that are ____________________________________________.
Traits can be inherited in ____________________________________________________.
Use the information from questions 19 and 23 to revise your model of heredity. On your model make sure to include what you predict a sibling of each the following shnorf would look like.
Part 3: Shnorf Genetics (the study of how traits are passed down)
Below are pictures of two shnorf siblings. Draw what you think their parents look like.

Sibling 1: Sibling 2:

Parent 1: Parent 2:

Were your predictions correct? Yes No
Where did sibling 1’s nose color come from?__________________________________________
What does this mean about the parents’ genes (genetic makeup) ? _______________________ _______________________________________________________________________________
If nose color were determined by one piece of genetic information, would it be possible for two green-nosed parents to have a blue-nosed offspring? Yes No
Justify your answer to number 29. ___________________________________________________ ______________________________________________________________________________________________________________________________________________________________
Could nose color be determined by two pieces of genetic information? Why or why not? ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
We are exploring the trait of ___________________________. The genetic information for traits are stored in ___________________________. Within a ___________________________, there are ___________________________ pieces of information; these are called ___________________________. ___________________________ code for the different versions of a trait; for example, ___________________________ and ___________________________. Even though the ___________________________ could be different in a ___________________________, only one will be seen.

What does this mean about how genetic information is passed down?______________________ ______________________________________________________________________________________________________________________________________________________________
What additional key points need to be included in a model of heredity?
Genetic information is stored in _______________________ which contain _______________________ and determines_____________________________________.
Not all alleles that are carried _________________________________________________.
Parents ___________________________________________________ to their offspring.
Use the information from question 34 to revise your model of heredity. In addition, make sure to include the following about the shnorf family consisting of two green-nosed parents, with blue-nosed AND green-nosed offspring:
The alleles which are contained in each family member’s genes. We will use ______ to represent the blue nose allele and ______ to represent the green nose allele.
The possible allele combinations that the parents could pass down to their offspring.
The fraction of offspring that are expected to show green noses, and the fraction of offspring that are expected to show blue noses.

Part 4: Predicting the Frequency of Traits - Shnorfs
Geneticists use __________________________ to calculate the fraction of siblings that will inherit a certain trait from their parents. Confirm that your model matches the fractions from this method. _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________
The following are eight siblings which are offspring from the parents we have been studying. Do these offspring match our predictions from question 35 and why? ______________________________________________________ ______________________________________________________ ______________________________________________________ ______________________________________________________ ______________________________________________________
When is our model the most accurate? ______________________________________________ _______________________________________________________________________________

	Green Nose	Blue Nose
Predicted Fraction (out of 8)
Actual Fraction (out of 8)

The terms dominant and recessive are often used in discussing the inheritance of traits. What do you think these terms mean?_______________________________________________________ _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
What additional key points need to be included in a model of heredity?
If the allele is dominant, ______________________________________________________ _________________________________________________________________________
If the allele is recessive, ______________________________________________________ _________________________________________________________________________
Punnett squares give ________________________________________________________ ____________________________________________________________________________________________________________________________________________________
Use the information from question 40 to revise your model of heredity. On your model, include a Punnett square to show the probability that two shnorf parents, one with tusks (allele “T”) and one with no tusks (allele “N”), would have offspring with tusks. Having tusks is known to be a recessive trait.

Part 6: Applying the Model
What patterns have you noticed in sets of human siblings?_______________________________ ______________________________________________________________________________
What patterns have you noticed between parents and their children?_______________________ _______________________________________________________________________________
Use your model to make a claim about which type of reproduction humans undergo. Humans undergo sexual reproduction asexual reproduction because ________________________________________________________________________ _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
According to your model, what does this mean about a human child’s genes?_________________ ______________________________________________________________________________________________________________________________________________________________
In humans, the allele for freckles is known to be dominant. Use your model to calculate the probability that two parents without freckles will have a child with freckles. ______________________________________ ______________________________________ ______________________________________ ______________________________________ ______________________________________ _______________________________________________________________________________
