n the red spotted butterfly there are two traits under investigation.  The wing margin can be either notched (N) or straight (n) and the wing color can be either pale yellow (b) or bright yellow (B).  A bright yellow male with straight wing margins was crossed with a bright yellow female with notched wing margins.  All of the resulting progeny had notched wings and both color patterns were present.  From these data determine the genotypes of the butterflies used in the original 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.
