How many alleles in human genome

WebSep 8, 2024 · For me this is actually different from 31 alleles as someone could have more than one mutation, resulting in 2^31 = 2 billion possible alleles. And we also have alleles that were not documented. As the chance of a specific gene suffer mutation from all the genes we have is low, I would say that more than 1 mutation has a very low chance. WebFor any gene, a person may have the same two alleles, known as homozygous or two different ones, known as heterozygous.
