Gene to Protein

A father rabbit had long ears while the mother rabbit had short ears. Which of these statements explains why one of the baby bunnies could have long ears?

• The baby bunny inherited its copies of the gene for ear length from its father and NOT from its mother. Those genes connect together to make its ears long.

• The baby bunny inherited its copies of the gene for ear length 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 ears long.

• The baby bunny inherited one copy of the gene for ear length from its father and one copy from its mother. That gene combination instructs for proteins that connect in ways that make long ears.

• The baby bunny inherited one copy of the gene for ear length from its father and one copy from its mother. Those genes connect together to make its long ears.

A shark pup has a pointed fin. Its mother also had a pointed fin, but its father had a rounded fin. Which of these statements explains why the shark pup has a pointed fin?

• The shark pup inherited one copy of the gene for fin shape from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make its fin pointed.

• The shark pup inherited one copy of the gene for fin shape from its mother and one copy from its father. Those genes connect together to make its fin pointed.

• The shark pup inherited its copies of the gene for fin shape from its mother and NOT from its father. Those genes connect together to make its fin pointed.

• The shark pup inherited its copies of the gene for fin 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 fin pointed.

Brayden is trying to figure out how petal shape is determined in two different roses. In the pink rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are different from each other. How does this affect how many types of proteins there are in each petal cell?

• The pink rose has one type of protein for the petal shape feature. The yellow rose has two types of protein for the petal shape feature.

• The pink rose has one type of protein for the petal shape feature. The yellow rose has one type of protein for the petal shape feature.

• The pink rose has two types of protein for the petal shape feature. The yellow rose has two types of protein for the petal shape feature.

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

A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?

• 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 connect in ways that make curly wool.

• 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.
