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?

Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis. Make sure you label the alleles for genes on the chromosomes the whole way through - every chromatid should have labeled alleles. For meiosis, both crossing over and independent assortment can occur. For the purpose of this exercise, assume that there is a single crossover event on the long chromosome between the A and D genes. Only show crossing over after its fully occured. There are no crossover events on the short chromosome. Regarding independent assortment, there are two possible outcomes in meiosis if there are two homologous pairs of chromsomes. Include both independent assortment possibilities - one on the left side and one on the right. Fill in the possible gamete genotypes for each outcome. If you do this correctly you should end up with 8 different types of gametes.
