Rule of Segregation Only one gene of the two alleles that you have is put into each gamete that you make. Alleles are located on homologous chromosomes, and since homologous chromosomes are segregated during meiosis, the genes are also segregated. Numerous gametes are formed during gamete production, and if the alleles are different (heterozygous), 50% of the gametes will carry one gene and 50% of the gametes will carry the other. When alleles are the same (homozygous), 100% of the gametes will carry the same allele. 1. A parent possesses two copies of each gene. When this parent passes on its alleles for a gene, how many does it contribute to each of the offspring? 2. How many copies of a gene does the other parent contribute to each offspring? 3. How many copies of each gene for the trait does each offspring receive?
