In fruit flies, eye shape is an X-linked trait. Round eyes (XG) are dominant to almond-shaped eyes (Xg). In the P generation, an almond-eyed male mates with a female that is homozygous for round eyes. What is the expected phenotype ratio (in percent) of the F2 generation from this cross? Round-eyed female:               100 75   0   50   25        Round-eyed male:                 25 0 75 100 50           Almond-eyed female:                 0 75   25   50   100        Almond-eyed male:                 0 100 75 50 25

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.
