7.2: Populations Flashcards
gene pool
the total/all number of alleles in a population
population of alleles
gene pool
Allele frequency
the number of a particular allele of a particular gene in the gene pool
the number of a particular allele of a particular gene in the gene pool
Allele frequency
Genotype frequency
number of individuals who are AA, Aa, or aa within the gene pool
number of individuals who are AA, Aa, or aa within the gene pool
Genotype frequency
State the Hardy-Weinburg equation in words
The genetic variation in a population will remain constant from one generation to the next, and so genotype frequency always stays the same
What are five conditions that must be met for the hardy-weinburg equation to be true
1- no genetic mutations occur
2- all genotypes must be equally fertile, so that no selection occurs
3- mating is random
4- population is large
5- no immigration or emigration
What is the hardy weinburg equation for allele frequency
p + q = 1
where p and q are the 2 different alleles
What is the hardy weinburg equation for genotype frequency
p² + 2pq + q² = 1
where p and q are the 2 different alleles (homozygous for squared and heterozygous for 2pq)
