Bialleellinen refers to a genetic condition where an individual has two alleles for a particular gene, one inherited from each parent. This is the most common genetic condition in humans, as humans typically have two copies of each gene, one on each of the 22 pairs of autosomes and one on each of the two sex chromosomes. The term "bialleellinen" is derived from the Latin word "bi," meaning two, and "allele," which refers to a variant form of a gene.

In a bialleellinen individual, the two alleles for a particular gene can be either identical (homozygous) or different (heterozygous). If the alleles are identical, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous for that gene. The expression of a particular trait is determined by the combination of alleles present.

Bialleellinen inheritance is the basis for many genetic disorders and traits, such as sickle cell anemia, cystic fibrosis, and blood type. Understanding bialleellinen inheritance is crucial in fields such as genetics, medicine, and evolutionary biology.
