In fruit flies, normal wings (G) are dominant to glossy wings (g) and red eyes (R) are dominant to clear eyes (r).  This trait is controlled by autosomal alleles. A male fly that is homozygous for normal wings and has clear eyes mates with a female fly that has glossy wings and is homozygous for red eyes. What is the expected phenotype ratio (in percent) of the F2 generation from this cross? Normal/Red: 18.75 6.25 9 56.25   Normal/Clear:  3 18.75 56.25 6.25   Glossy/Red: 56.25 6.25 3 18.75   Glossy/Clear: 56.25 1 6.25 18.75

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.
