A female from a pure-breeding strain of Drosophila with vermillion-colored eyes is crossed with a male from a pure-breeding wild-type, red eyed strain. All the F1 males have vermillion-colored eyes, and all the females have wild-type red eyes. What conclusions can you draw about the mode of inheritance of the vermillion trait, and how could you test them? Show solution.

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.
