As it is

UNIT GENETICS PROBLEMS #2: TEST CROSSES 1. In peas, green pods are dominant and yellow pods are the recessive trait. You have pea plants with green pods but you are unsure of the parentage of these plants. How would you determine the genotype of your green pod plants 2. Two black mice mate. Six of their offspring are black and two are white. (Black fur is dominant to white.) a· What are the genotypes of the parents. b. For which offipring are you sure of the genorypes! 一一& 3. In rabbits, the allele for brown coat is dominant, the alliele for white coat is recessive. Suppose you have a group of rabbits, some brown and some white. If you want to find out the genotype of a brown rabbit, what color rabbit would you mate it with? 4. A brown buck (male) is mated with a white doe (female). In their litter of 11 young, six are white and five are brown. Brown is dominant to white. a. What is the genotype of the buck h What ratio of brown and white offipring would have been produced by the above mating if the brown buck had been homozygous? 27
