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.

Genetic loci and genetic markers are fundamental concepts in genetics and genomics. Learn how loci define genomic positions and how genetic markers such as SNPs, STRs, and VNTRs are used to study inheritance, genetic variation, linkage, disease-associated regions, population genetics, and genome-wide variation.
