Weballele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait. The combination of alleles that an organism carries constitutes its genotype. If the paired alleles are the same, the … WebGregor Mendel's principles of heredity, observed through patterns of inheritance in pea plants, form the basis of modern genetics.
