26.

Three tigers have different parents. They all have the same proteins for stripe pattern in their cells. What can you say about the tigers' stripe patterns?

a)

They will have the same stripe patterns since all tigers have the same stripe patterns.

b)

They will have the same stripe patterns since their proteins for stripe pattern are the same so the proteins will connect in the same way.

c)

They will have different stripe patterns because even with the same proteins for stripe pattern, the proteins can connect in different ways.

d)

They will have different stripe patterns since only offspring from the same parents have the same stripe patterns.

27.

Two goldfish have different parents. One fish has a split tail and the other does not. Why do the goldfish have tails with different shapes?

a)

Each goldfish has a different tail shape because offspring from different parents will have different tail shapes.

b)

Each goldfish has a different tail shape because they have different versions of the gene for tail shape that connect together to make different tail shapes.

c)

The goldfish have different versions of the gene for tail shape. The genes are split inside one goldfish’s tail but not inside the other’s.

d)

The goldfish have different versions of the gene for tail shape, which instruct for different proteins that connect in different ways to make different tail shapes.

The goldfish have different versions of the gene for tail shape, which instruct for different proteins that connect in different ways to make different tail shapes.

28.

A young goat has downward-curved horns. Its father has upward-curved horns while its mother has downward-curved horns. Which of these statements explains why the young goat has downward-curved horns?

a)

The young goat inherited one copy of the gene for horn shape from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make downward-curved horns.

b)

The young goat inherited one copy of the gene for horn shape from its mother and one copy from its father. Those genes connect together to make its downward-curved horns.

c)

The young goat inherited its copies of the gene for horn shape from its mother and not from its father. Just like its mother’s genes, those genes instruct for proteins that connect in ways that make its downward-curved horns.

d)

The young goat inherited its copies of the gene for horn shape from its mother and not from its father. Those genes connect together to make its downward-curved horns.

The young goat inherited its copies of the gene for horn shape from its mother and not from its father. Those genes connect together to make its downward-curved horns.

29.

There are two junco birds that each have different proteins in their cells for beak pointiness. They have different parents. What can you say about the birds' beak pointiness?

a)

They will have the same beak pointiness because even with different proteins for beak pointiness, the proteins can connect in the same way.

b)

They will have different beak pointiness since offspring from different parents will havedifferent beak pointiness.

c)

They will have different beak pointiness since their proteins for beak pointiness are different so the proteins will connect in different ways.

d)

They will have the same beak pointiness since all junco birds have the same beak pointiness.
