Homozygosity refers to having identical alleles for a single trait.
In genetics, homozygosity is a fundamental concept that describes the condition when an individual has two identical alleles for a specific gene or trait. Alleles are different versions of a gene and an organism inherits one allele from each parent for each gene.
When both alleles for a particular trait are the same, it results in homozygosity. This can be either homozygous dominant, where both alleles are dominant (e.g., AA) or homozygous recessive, where both alleles are recessive (e.g., aa).
In an overall, homozygosity plays a crucial role in the expression of genetic traits, as it determines whether a trait will be dominant or recessive in an individual.
