You have just discovered a new species of squirrel with red eyes! In addition, you have determined that red eyes are a recessive trait that follow Mendelian patterns of inheritance. The dominant trait results in dark brown eye color. You observe a red eyed female squirrel with two offspring: one with red eyes and the other with dark brown eyes. What is the genotype of the father?

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.
