In butterflies, blue wings (B) are dominant over yellow wings (b), and stripes (S) are dominant over no stripes (s). These genes for these two characteristics assort independently. A homozygous butterfly with yellow wings and no stripes is crossed with a homozygous butterfly that has blue wings and stripes. Afterward, individuals from this F1 generation were crossed obtaining a total of 272 butterflies as follows: 135 blue-winged butterflies with stripes, 55 blue with no stripes, 57 yellow with stripes, and 25 yellow without stripes.

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.
