Using the Hardy–Weinberg Principle (OCR A-Level Biology A): Flashcards

All alleles for a particular gene in a population

Frequency of dominant allele

Frequency of recessive allele

p + q = 1

p² + 2pq + q² = 1

Frequency of homozygous dominant genotype

Frequency of heterozygous genotype

Frequency of homozygous recessive genotype

Allele frequencies remain constant across generations

No migration, mutation, selection, drift; large random breeding
