Question

Tail length in mice varies within a population. Scientists observed change in the distribution of tail lengths in a mouse population over time. At the genetic level, what has most likely happened to the allele for the shortest tail lengths?

A The allele changed from being dominant to being recessive.
B The allele changed from being autosomal to being sex-linked.
C The allele became less frequent than the alleles for longer tail lengths.
D The allele began to code for long tail lengths instead of the shortest ones.

Answer 1

C

Step-by-step explanation:

the best option would be C

Answer 2

The answer to the given question above would be the third option. If tail length in mice varies within a population and scientists observed change in the distribution of tail lengths in a mouse population over time, at a genetic level, the one that has most likely happened to the allele for the shortest tail lengths is that, the allele became less frequent than the alleles for longer tail lengths. Hope this helps.
