15. B. You set up a cross between a male fruit fly with lobe eyes and a true breeding female fruit fly with reduced bristles and disrupted wings. In the F1 offspring you see the all the flies have WT bristles and WT wings. However, half the flies have WT eyes and half the flies have lobe eyes. You take 20 of the F1 female flies with lobe eyes and mate them to 20 true breeding male flies with reduced bristles and disrupted wings and observe the following offspring: 164 lobe eyes and reduced bristles 137 lobe eyes and disrupted wings 638 reduced bristles and disrupted wings 152 reduced bristles 40 wildtype 175 disrupted wings 659 lobe eyes 35 lobe eyes reduced bristles and disrupted wings Calculate the interference for this region.

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.
