An insect from a strain breeding for white eyes (RRww) was crossed to an insect from a strain breeding for cream eye (rrWW). The F1 all had red eyes. The F1s were intercrossed to produce F2 generation that consisted of 175 red eyed:81 white eyed. Provide the genetics of inheritance of this trait. Provide the genotypes for the F1s and F2s of this cross.

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.
