WebTo be exact, the two copies of a gene carried by an organism (such as a Y and a y allele) are located at the same spot on the two chromosomes of a homologous pair. Homologous chromosomes are similar but non-identical, and an organism gets one member of the pair from each of its two parents. WebAug 17, 2024 · Remember, a chromosome carries genes in linear order; a gene is a segment of code that dictates what trait will develop; and alleles are forms of a gene.
