How many alleles are in a gene
WebDifferent variations of a gene are called alleles. Each parent passes one allele to the child for each gene. The combination of alleles someone has will determine what proteins are made. How many alleles do humans have? Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each ... 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 …
