Homozygosity

Homozygosity is a genetic condition which results when both copies of a gene (alleles) are the same. This can lead to an increased risk of developing certain genetic diseases, such as cystic fibrosis. Homozygosity is also important in assessing the genetic relationships between individuals in a population and can be used in DNA paternity testing. It is an important tool for scientists and medical professionals, helping to better understand how genetic mutations can cause disease or reveal genetic relationships.
