Genotype frequencies describe the proportion of individuals in a population carrying particular genetic combinations. Learn how genotype frequencies relate to allele frequencies and how mating patterns, Hardy-Weinberg equilibrium, selection, genetic drift, inbreeding, gene flow, population structure, and breeding influence genotype distributions.

Multiple alleles occur when a gene exists in more than two alternative forms within a population. Learn how multiple alleles influence genotype and phenotype, including the ABO blood group system, codominance, recessive inheritance, genetic variation, allele frequencies, and population genetics.

Codominance and incomplete dominance are inheritance patterns that demonstrate how different alleles can interact in heterozygous individuals. Learn how codominant alleles can be expressed together, how incomplete dominance produces distinct or intermediate phenotypes, and how these patterns relate to Mendelian inheritance.

Dominant and recessive inheritance explains how different alleles influence inherited traits and genetic disorders. Learn how homozygous and heterozygous genotypes, allele segregation, fertilization, gene dosage, penetrance, and genetic interactions shape patterns of inheritance.

Homozygosity and heterozygosity describe whether the two alleles at a genetic locus are identical or different. Learn how these genetic states influence inheritance, genetic variation, disease genetics, inbreeding, population genetics, and genomic analysis.
