In horses, grey coat color is determined by a dominant allele. A herd of 50 horses is observed to have 20 grey horses. Determine each of the following values for this herd.

I think it'd be 30/20 which is a 3:2 ratio.

Explanation:

Gray is dominant, therefore a single copy of the gray allele will cause a horse to turn gray. If a horse has two copies of gray, all offspring of this horse will be gray.

autosomal

explanation:

is a term used in genetic genealogy to describe dna which is inherited from the autosomal chromosomes
