Homologous chromosomes contain the same genes and the same locations, or loci but may have different alleles. But jsut so this definition makes sense, lets define some of the words. A gene contains the traits that is passed down from two parents to its offspring. An allele is one part of a pair of genes that are located in a particular spot that controls the same trait.
Homologous chromosomes are matched pairs of chromosomes that carry the same genes at the same loci, each inherited from different parents. Genes provide the traits for an organism, and alleles are the variations of those genes. Homologous chromosomes may have the same alleles (homozygous) or different alleles (heterozygous) for the same gene.
