Select the exception. 12 options: 13 (5 points) A woman is found to have 47 chromosomes including three X chromosomes. Which of the following describes her expected phenotype? 13 options: 14 (5 points) Which of the following is an example of polygenic inheritance? 14 options: 15 (5 points) Why did the F1offspring of Mendel’s classic pea cross always look like one of the two parental varieties? 15 options: Page 5 of 7 Page 6 of 7 16 (5 points) Use the following information to answer the s below. Tallness (T) in snapdragons is dominant to dwarfness (t) while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) flower color. A dwarf red snapdragon is crossed with a plant homozygous for tallness and white flowers. What are the genotype and phenotype of the F1individuals? 16 options: 17 (5 points) National Basketball Association (NBA) scientists have identified the gene for superior athletic ability. The allele A represents the dominant form of the gene while the allele a represents the recessive form of the gene. The scientists find that the superior athletic ability gene is optimally expressed in individuals who possess the homozygous dominant form. If Michael Jordan who has the Aa genotype has a child with a woman who has the aa genotype what are the chances that his child will inherit the optimal superior athletic ability genotype? 17 options: 18 (5 points) There is evidence that a certain color in cats is sex-linked. Yellow is recessive to black. A heterozygous condition results in tortoise shell or calico color. A calico cat has a litter of 8 kittens: 1 yellow male 2 black males 2 yellow females and 3 calico females. What was the male parents probable color? 18 options: Page 6 of 7 Page 7 of 7 19 (5 points) Imagine you are performing a cross involving seed color in garden plants. What F1 offspring would you expect if you cross true-breeding parents with green seeds with true-breeding parents with yellow seeds? 19 options: 20 (5 points) All of the genes located on a given chromosome constitute a 20 options: Page 7 of 7
