<span>From the proportions of phenotypes in the offspring. If Genes would be equal you would get 1/4 A, 1/4 B and 1/2 AB; but you often get 1/4 A and 3/4 B. </span>I hope that this is the answer that you were looking for and it has helped you.
Is this like on a test or like homeowork?
Say B is the genotype for example. If her whole family is attached, then she would be Homozygous Dominant. For example, BB.
