Web11 de abr. de 2024 · Definition. 00:00. …. Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked. WebAlleles are located on chromosomes, which are the structures that hold our genes. Specifically, alleles influence the way our body’s cells work, determining traits and … 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. highline quarter

WebDifferent alleles of the same gene are distinguished with a number following a hyphen (abc4-1 and abc4-2). When only a single allele is known, the hyphen is not needed. Thus abc3 = abc3-1 if only a single allele is known. The same rules of nomenclature apply to both dominant and recessive mutations.
