so each gamete receives only one from each pair of chromosomes. Thus, the parents' diploid cells have two copies of each gene, but each haploid gamete has only one copy of each gene. stick that is facing up indicates which chromosome from each homologous pair is included in the gamete. The alleles from this chromosome are recorded in the Egg or Sperm column in the charts on page 4. When a haploid sperm fertilizes a haploid egg, this produces a diploid zygote with one copy of each gene from the mother and one copy from the father. These genes determine the phenotypic traits of the baby dragon that develops from this zygote. The dragon parents record the phenotypic traits of their baby in the Baby's Traits column in the charts on page 4. SIMULATION PROCEDURE
