How many alleles in human genome
WebAug 20, 2024 · The human genome began with the assumption that our genome contains 100,000 protein-coding genes, and estimates published in the 1990s revised this number … WebThe short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles.
