You are doing a genetics experiment with the fruit fly. In the “P” generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Assume the genes are not found on a sex chromosome. Indicate the body color alleles with B and b and the wing size alleles with N and n.   a) The genotypes of the flies in the P generation are: Female: ______________ Male: ______________   b) The genotype of the flies in the F1 generation is: _____________   c) You now take an F1 female and cross her to a true-breeding black, wingless male. This male’s genotype is: ______________

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.
