*Genetics Matt observed 80 green frogs and 20 brown frogs. He knows from published studies, brazilian frog coloration derives from two alleles (p=green and q=brown). After genotyping the green frogs he finds they are homozygous for the p allele. What percentage of heterozygous frogs should he expect to find?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
