Question

Which observation is true about organisms that carry the same genes?

a) They will not have the same phenotype if there are differences in expression of the genes
b) They will not have the same phenotype, even if the genes are all expressed in the same way
c) They will have the same phenotype, because they will express the same genes
d) They will not have the same phenotype, even if there are differences in expression of genes

Answer 1

The phenotype of organisms with the same genes may not be the same if there are differences in gene expression.

Step-by-step explanation:

When organisms carry the same genes, their phenotype may not be the same if there are differences in the expression of the genes. This means that even though they have the same genetic makeup, external factors can cause genes to be expressed differently, leading to different observable traits. Therefore, option a) is true.
