Hardy-Weinberg Equilibrium and Genetic Drift

These flashcards cover key concepts of Hardy-Weinberg Equilibrium and Genetic Drift as discussed in the lecture.

Hardy-Weinberg Equilibrium

A principle that describes the conditions under which a population's allele and genotype frequencies remain constant from generation to generation.

Conditions for Hardy-Weinberg Equilibrium

1. No mutation 2. No immigration or emigration 3. No survival or reproductive advantage 4. Random mating 5. Infinite population size.

Genetic drift

random changes in genotype frequencies in generations

When is genetic drift more likely to occur?

Genetic drift is more likely to occur in small populations due to random chance events. genotype frequencies are less likely in a population with greater amounts of people

Impact of immigration on genetic drift

In small populations, the effect of immigration can alter genotype frequencies, contrasting with small populations without immigration.
