Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered the evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time.

Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Explanation:
If the father had the gene BB (purebred & not carrying colourblind allele), then the answer will be a). All of their children will have normal vision with half of them carrying the colourblind allele.
If the father had the gene Bb (hydrid & carrying colourblind allele), then the answer will be d). 3/4 of their children would have normal vision whilst the last quarter would have colourblind males. This is due to them having to receive one colourblind allele from their mother on the X chromosome & one colourblind allele from their father on the Y chromosome.
