The Dracula gene makes mice active at night and only consume blood instead of normal food.  You cross a normal black mouse with a vampire mouse. The first generation are all black, but then you cross F1 mice together and collect all the litters. You find that the F2 generation has 138 black mice, and 62 vampire mice.

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.
