8- A Martian creature called a gazook has 17 pairs of chromosomes. Three genes for three traits are considered: eyeball gene with two alleles, round and square (R, r); tail gene with two alleles, hairy and smooth (H, h); and toe gene with two alleles, 9 toes and 11 toes (T, t). Round eyeballs, hairy tails and 9 toes are dominant to square eyeballs, smooth tail and 11 toes. A male has offspring with a gorgeous female who has square eyeballs, a hairy tail and 9 toes on each of her three feet! She gives birth to 200 little gazooks, who have the following phenotypes: - 100 have round eyeballs, 100 have square eyeballs - 100 have hairy tails, and 100 have smooth tails - 150 have 9 toes, and 50 have 11 toes What is the chance that in the future, this couple will have an offspring who is not phenotypically identical to either of the parents? Hint: Calculate the chance for the offspring to be phenotypically identical to either of the parents, then subtract it from 100%. A- 12.5% B- 25% C- 50% D- 62.5% E- 75% F- 87.5%

9- In the question above, what is the chance that this couple (couple A) will have a child, who is a boy, genotypically identical to one of the parents (mom or dad), and a child, who is a girl phenotypically identical to one of the parents (mom or dad)?

A- 3/16 chance for the girl, and 1/8 chance for the boy

B- 1/4 chance for both

C- 1/2 chance for the girl, and Â½ chance for the boy

D- 1/8 chance for the girl, and 3/16 chance for the boy

E- 1/8 chance for the girl, and 3/8 chance for the boy

F- 1/16 chance for both

10- In the scenario above, another couple (couple B) and their 200 little gazooks move in the next door house. All the little gazooks are phenotypically identical to their father. The female is a supermodel who has square eyeballs, a smooth tail, and 11 toes on each of her three feet, and the male has round eyeballs, a hairy tail, and 9 toes. One year later, both Mrs. A and Mrs. B get pregnant, and each one gives rise to 200 new gazooks in the following year. The new children of couple A, all have round eyeballs, hairy tails, and 9 toes. Some of the new children of couple B have square eyeballs, smooth tails and 11 toes. What is the genotype of Mr. B, and which of the following is true?

A- Mr. B is âRrHHTTâ, and he did not have an affair with Mrs. A

B- Mr. B is âRRHHTTâ, and he had an affair with Mrs. A.

C- Mr. B is âRRHHTTâ, and Mr. A had an affair with Mrs. B.

D- Mr. B is âRRHHTtâ, and he had an affair with Mrs. A.

E- Mr. B is âRRHHTtâ, and both Mrs. A and Mrs. B have some explaining to do because of the night they spent in a bar when both Mr. A and Mr. B had gone to a bachelor party together.

F- B and C are correct

G- D and E are correct
