3. a. Why are most populations not in Hardy Weinberg Equilibrium?   b. There is an ancient village population of humans. We know very little about this population. How can we use genetics to determine if the societal system of the village was matrilocal or patrilocal?  c. There was variation in a rat phenotype (coat color.) The coat colors ranged from dark color coats to light color coats. As the rats migrated into the basements of campus, the light color rats were more likely to be caught by the campus cat. Over time, the basement rat population shifted to entirely dark color coats. This is an example of what kind of selection?  d. Explain how a genetic bottleneck could lead to higher susceptibility of a disease, such cancer, in that population.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
