Allele Frequency, Hardy-Weinberg, and Genetic Drift

Front

What does it mean for a population to be in genetic equilibrium according to Hardy-Weinberg assumptions?

Back

It means the population is not evolving.

Front

What is the term for the movement of alleles from one population to another?

Back

Gene flow.

Front

True or False: Adaptations are features you are born with that can help or hurt you in your environment.

Back

True.

Front

What are the five Hardy-Weinberg assumptions?

Back

1. Large population size 2. No mutations 3. No gene flow 4. Random mating 5. No natural selection.

Front

What is genetic drift?

Back

A mechanism of evolution that refers to random changes in allele frequencies in a population.

Front

How does gene flow affect genetic diversity in populations?

Back

Gene flow increases genetic diversity by introducing new alleles into a population.

Front

What is the significance of mutations in evolution?

Back

Mutations are the source of new genetic variations that can lead to evolution.

Back

To predict the genetic variation of a population under ideal conditions.
