In the X linked fruit fly cross , why were the adult flies in the XRXr x XRY vial removed? 1. Adult fruit flies are known to eat their larvae and this would throw off the count 2. The goal was to count the phenotypic ratio of the offspring; therefore the parental generation must be removed. 3. The adult flies would eat all the food and the offspring would die before a count could be made

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.
