Evolution of Gene Pools Flashcard

Front

What is the frequency of the recessive genotype if 64% of the population has the recessive phenotype?

Back

.64

Front

In the equation p + q = 1, what does p represent?

Back

Frequency of dominant allele

Front

What does it mean when a gene pool of a population changes?

Back

The population is undergoing evolution

Front

What is the total collection of genes in a population at any one time called?

Back

Gene pool

Front

If 64% of the population has the recessive phenotype, what is the frequency for the homozygous dominant genotype (RR)?

Back

.04

Front

Define gene flow.

Back

The transfer of genetic variation from one population to another.

Front

What is allele frequency?

Back

The relative frequency of an allele at a genetic locus in a population.

Front

What is genetic equilibrium?

Back

A state where allele frequencies in a population remain constant over generations.

Front

What is the Hardy-Weinberg principle?

Back

A principle that describes the genetic variation in a population that is not evolving.

Front

What factors can lead to changes in a gene pool?

Back

Natural selection, genetic drift, mutation, and gene flow.
