All diploid organisms have two alleles at a given locus on a pair of homologous chromosomes. Because haploid cells (e.g., oocyte and spermatozoa in humans) contain half the chromosome compliment, such cells contain only one allele of each gene.

Chromosomes that carry the same genes are termed homologous chromosomes. The alleles on homologous chromosomes may differ, as in the case of heterozygous individuals. Organisms (normally) receive one set of homologous chromosomes from each parent.

Alleles: The different forms taken by a given gene is called alleles, which contain slightly different genetic information that determines the same character (The color of the pea plant: Purple allele and white allele).

allele: An alternative form of a gene. Alleles give different phenotypic expression of a gene by having different DNA sequences from one another. ... homologous chromosomes: Chromosome pairs which contain genes for the same traits at matching loci; they have the same length, centromere position, and staining patterns;
