In a population of pika, you find that individuals vary in their fur color - there are greyish and black pikas. The genetic mechanism behind fur color is mainly regulated by one gene Attractie, and in this population there are only two alleles for the Attractie gene: A1 and A2. Greyish fur color is better camouflaged when they inhabit in talus (broken rocks); black fur helps protect them against predators in coniferous forests, where pika makes burrows under fallen logs and tree stumps. Why might you hypothesize that this pika population is not in Hardy-Weinberg equilibrium? What do you think is happening? Clearly explain your reasoning.

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.
