Question

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?
Responses

a
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 two types of protein for the petal shape feature.

b

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.

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

Answer 1

Answer: a

Explanation: The pink rose is homozygous (both gene copies the same), so the cell makes one version of the protein. The yellow rose is heterozygous (two different alleles), so the cell can make two different protein variants (one from each allele).
