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.

Mendelian genetics explains the fundamental principles of genetic inheritance. Learn how genes and alleles are transmitted through meiosis and fertilization, including segregation, independent assortment, dominance, genotype and phenotype, Punnett squares, and major Mendelian inheritance patterns.

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.

Genes and alleles form the foundation of inherited variation in animal breeds. Learn how genetic variation influences traits, breeding, adaptation, genetic diversity, and population structure.
