Refer to the picture below. this is an example of:

select one:
a. homologous structures
b. vestigial structures
c. sequential structures
d. analogous structures

The answer is a. homologous structures

Explanation:

Homologous Structures:

Structures that have similar anatomy or similar structure but have different functions are called homologous structures.

These structures indicate shared ancestry between the animals in question. This means that the structures may be used for different functions but they are encoded by same or similar genes.

The bones in the picture perform quite different functions and they might look different from the outside but as we look closer, the bone structure and joints are similar. This shows that all of these animals evolved from a common ancestor.

well we can't tell you because we cant see the time give a screen shot or something.

b is dominant over the allele for the white fur.
