Question

In another species of mouse found in the Sand Hills of Nebraska, we have a similar phenotypic story with light mouse coloration resulting from selection due to living on light colored surfaces. As in the previous case, it was found that an allele at the AGOUTI locus is involved in this phenotypic difference. A derived allele a has been fixed in the Sand Hill populations relative to the ancestral allele a that is fixed in the other ancestral populations. measured allele-specific transcription levels of AGOUTI in the various genotypes of mice. The data are shown below

Explanation / Answer

1. Dominant mutation is expressed in a ab vs a+ allele. The phenophytic effect of the mutation is that most of the mice have developed the light coloured coat due to the mutation in the allele and formation of a ab instead of a+ seen in the ancestral population.

2. Depending on the homozygous genes and heterozygous genes of dark coloured meerkats and light coloured meerkats are crossed variety of species are formed wherein few dark colored and some light colored meerkats are formed.inration of 3:1 depending on the homozygous and heterozygous conditions of the alleles.

The type of inheritance observed is dominant type of inheritance.
