This is a family of birds. The gene versions for the mother and father are shown above. If these parents had offspring...
1. What are the two possible gene versions that the offspring A would have? How about offspring B?
2. What trait would offspring A have? What trait would offspring B have?
3. Why does offspring C have a different trait?

These frogs are sisters and share the same parents. They have two different traits for color (dark red and green). Explain how the frog's genes determine their color (trait). Assume that this DID NOT come from a mutation. Be detailed.
Here are some words that you may use, but don't have to: gene, offspring, trait, protein, variation, feature, parents

These two goldfish have different parents. One has a split tail, while the other does not. Why do the goldfish have tails with different shapes?
Each goldfish has a different tail shape because...
... offspring from different parents always have different tail shapes.
... the genes connect in different ways to create different tail shapes.
... the fish have different genes, which are the instructions for different tail shape proteins.
A father sheep has curly wool. The mother sheep has straight wool. Which of the following statements explains why their baby lamb has curly wool?
The baby lamb inherited both copies of its wool texture genes from its father and none from its mother.
The baby lamb inherited one copy of the wool texture gene from its father and one copy from its mother. The genes are instructions for proteins that connect in ways to make curly wool.
The baby lamb inherits one copy of the wool texture gene from its father and one copy from its mother. The two gene copies connect to each other and create curly wool.
In wolves, tooth size is determined by their genes. Wolf #1 has tooth genes that are different from one another (heterozygous, T1 T2). Wolf #2 has tooth genes that are the same (homozygous, T2 T2). How does this affect the number of proteins in each tooth cell?
Wolf #1 has one protein for tooth size. Wolf #2 has two proteins for tooth size.
Wolf #1 has one protein for tooth size. Wolf #2 also has one protein for tooth size.
Wolf #1 has two proteins for tooth size. Wolf #2 has one protein for tooth size.
Wolf #1 has two proteins for tooth size. Wolf #2 also has two proteins for tooth size.
Shakira reads an article about a family of wildcats. One of them has a mutation for tooth sharpness. Which of the statements about the wildcat with the mutation is DEFINITELY 100% true?
There must be a change in the wildcat's genes.
The wildcat must have sharper teeth.
There is no change to the wildcat's teeth.
The wildcat must have less sharp teeth.
