👉 Bi-allelically, a term that means both genes are identical, is a phenomenon where two different genes have the exact same sequence of nucleotides at their respective positions. This can be referred to as "an identical twins" in genetics.
Example: In a genetic test for someone who has two copies of a gene called "ARAF", it's likely that they both carry the same variant of this gene, just with slightly different copies. This term is used in medical fields to describe individuals who have shared the same genetic mutations over generations, which can lead to disorders like Huntington's disease or cystic fibrosis. It’s an eerie, yet fascinating concept that could potentially be a major issue in genetics research if not managed properly.
