In cattle, the hornlessness (hornlessness) gene dominates over the horniness gene. What phenotype

In cattle, the hornlessness (hornlessness) gene dominates over the horniness gene. What phenotype and genotype will the offspring have from crossing a horned bull with a homozygous hornless cow?

Let’s designate the gene that causes the absence of horns in cows as C, then the gene that leads to the development of horns in the homozygous variant will be c.

A horned bull will be recorded as cc, since homozygosity is a prerequisite for the phenotypic realization of this trait. It will produce the same type of sperm with.

Polluted cows are homozygous according to the problem statement. They will record as CC and produce C. oocytes.

The offspring from the crossing of the described cows and a bull will look like this:

Cc – 100%, all calves will be heterozygotes and will not have horns.
