the genes are only standing straight up in the cells of one rabbit's ears

the rabbits have different versions of the gene for ear shape, which instruct for different proteins that connect in different ways

Offspring from different parents will always have different ear shapes

both copies come from dad

both copies come from mom

1 copy comes from mom, 1 copy comes from dad

the process is random, any of the 3 situations can happen

both wolves have 1 type of protein

both wolves have 2 types of protein

Wolf 1 was two types of protein, Wolf 2 has 1 type of protein

It is impossible to tell

They will have the same ear shape since their proteins are the same and connect in the same way.

They will have the same ear shape since all bears have the same ears.

They will have different ear shapes since only offspring from the same parents have the same ear shape.

there will be no change to the frog's poison

the frog will be more poisonous than the rest of its family

the frog will be less poisonous than the rest of its family

there must have been a change in the frog's genes.

The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.

The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Those genes connect together to make its wool curly.

The baby lamb inherited one copy of the gene for wool shape from its father and one copy from its mother. That gene combination instructs for proteins that make its wool curly.

The baby lamb inherited one copy of the gene for wool shape from its father and one copy from its mother. Those genes connect together to make its curly wool.

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

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.

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

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

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

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.

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.

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 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.

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.

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.

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.

There must have been a change in the wildcat’s genes.

The wildcat must have sharper teeth.

There will be no change to the wildcat’s teeth.

The wildcat must have less sharp teeth.

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

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

different beak pointiness.

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

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

The rabbits have different versions of the gene for ear shape. The genes are only standing straight up in the cells of one rabbit’s ears.

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

Each rabbit has a different ear shape because offspring from different parents will have different ear shapes.

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

The changed protein connects differently, but its function doesn’t change.

The changed protein connects differently, so its function changes.

The changed protein connects in the same way, but its function changes.

The amount of that type of protein stayed the same, so its function doesn’t change.

Wolf 1 has one type of protein for the tooth size feature. Wolf 2 has one type of protein for the tooth size feature.

Wolf 1 has two types of protein for the tooth size feature. Wolf 2 has one type of protein for the tooth size feature.

Wolf 1 has two types of protein for the tooth size feature. Wolf 2 has two types of protein for the tooth size feature.

It is impossible to say anything about proteins from the given information.

They will have the same ear shape since their proteins for ear shape are the same so the proteins will connect in the same way.

They will have the same ear shape since all bears have the same ear shape.

They will have different ear shapes because even with the same proteins for ear shape, the proteins can connect in different ways.

They will have different ear shapes since only offspring from the same parents have the same ear shape.

Each fruit fly has a different eye color because offspring from different parents will have different eye colors.

Each fruit fly has a different eye color because they have different versions of the gene for eye color that connect together to make different eye colors.

The fruit flies have different versions of the gene for eye color, which instruct for different proteins that connect in different ways to make different eye colors.

The fruit flies have different versions of the gene for eye color, and the genes are different colors in each fruit fly’s eyes.

The baby crawfish inherited one copy of the gene for tail length from its mother and one copy from its father. Those genes connect together to make its long tail.

The baby crawfish inherited one copy of the gene for tail length from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make a long tail.

The baby crawfish inherited its copies of the gene for tail length 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 a long tail.

The baby crawfish inherited its copies of the gene for tail length from its mother and not from its father. Those genes connect together to make a long tail.

The mosquitoes have different traits because they have different proteins for the body size feature in their cells. Differences in the structure of these protein molecules affect how they interact with other protein molecules, and this results in their different body sizes. I don’t know how gene combinations are involved.

The mosquitoes have different traits because they have different proteins for the body size feature in their cells. Differences in the structure of these protein molecules affect how they interact with other protein molecules. A gene provides instructions for making a protein, so mosquitoes with different genes will have different proteins in their cells that result in small, medium, or large body sizes.

The mosquitoes have different traits because they have different proteins for the body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. A gene version provides instructions for making a specific protein, so mosquitoes with different combinations of gene versions will have different proteins in their cells that result in small, medium, or large body sizes. Each parent randomly passes on one of its two copies of a gene for a feature, which is why each mosquito offspring can have a different combination of gene versions even though they have the same parents.
