Popular definitions of 'allele' typically refer only to different alleles within genes.

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. Web31 de mai. de 2024 · How alleles are written? The dominant allele is by convention written with a capital (upper case) letter. Recessive: In the heterozygous genotype, the expression of one allele is sometimes masked by another. The allele which is masked is said to be recessive. The recessive allele is by convention written with a lower case letter. durk pearson and sandy shaw 2022
