Population Genetics Flashcards
These are a group of individuals who share a common set of genes and live in the same geographic area.
Population
These are a set of all genes in a particular population or species.
Gene Pool
This concerns with the genetic traits in large numbers of people and follows the Hardy-Weinberg principle.
Population Genetics
These are the three genotype frequencies in a population.
- Homozygous Dominant
- Homozygous Recessive
- Heterozygous
These are the two allele frequencies.
Dominant and Recessive
This describes the frequency of occurrence or proportions of different alleles of a particular gene in a given population.
Allele Frequency
The formula for allele frequency.
Allele Frequency = # of copies of a specific allele / total # of every allele in the gene pool
This describes the proportion of a population with regards to their genotype divided by the entirety of a population.
Genotype Frequency
These are the three types of genotype frequencies.
- p2 (Homozygous D)
- q2 (Homozygous R)
- 2pq (Heterozygous)
This principle states that allele and genotype frequencies will remain constant from generation to generation given there is an absence of evolutionary influences.
Hardy-Weinberg Principle
This is the formula for allele frequency.
p + q = 1
This is the formula for genotype frequency.
p2 + 2pq + q2 = 1
This is the sum of all possible outcomes.

This where the problem lies and is considered the key to Hardy-Weinberg problems.
Homozygous Recessive
These are the 4 factors that can be observed in a population that drives evolution.
- Selection
- Migration
- Mutation
- Genetic Drift
