*Ms. Libby Davison bought three Congo Lily bulbs at a flower show after she was told they were each from different inbred lines. One had red flowers, on yellow flowers, and one white flowers. She determined that flower color was controlled by three alleles at a single gene. Red was found to be codominant with yellow, and both alleles dominant to white. Some of the crosses she made and the resulting progeny are listed below: Cross Red (selfed) Progeny All red

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.
