BIO392-01 FA19 Chapter 2 practice questions 2-1 In peas, the smooth allele is dominant over the wrinkled allele. A plant with round peas was crossed to a plant with wrinkled peas and all of the resulting plants had smooth peas. What are the genotypes of the parents in this cross? A) RR B) RR Rr C) Rr xr D) Rr x Rr E) т жт 2-2 In peas, the yellow allele is dominant over the green allele. A plant with yellow peas was crossed to a plant with green peas. The resulting plants were 50% yellow and 50% green. What are the genotypes of the parents in this cross? A) YY x yy В) YY и Ту C) Гу уу D) Yy x Yy E) уу х уу 2-3 Assuming independent assortment, what phenotypice ratio would you expect to see if an individual with the genotype RrGg is self-crossed? A) 1:3 B) 9:3:3:1 C) 1:2: D) 1:3:2: E) 3:1 2-4 In peas, axial (A) flower position is dominant to temminal (a), and tall (L) is dominant to short (). If a plant that is heterozygous for both traits is allowed to self-fertilize, how many of the offspring would also be heterozygous for both traits? A) 9/16 B) 1/4 C) 3/16 D) 1/8 E) 1/16 2-5 If a plant with purple, axial flowers and green, inflated pods is heterozygous for all four genes, how many different types of gametes can it produce? A) 1 В) 4 C) 8 D) 9 E) 16 2-6 The gene L detemines hair length in rabbits. The gene B determines hair color. A rabbit with long, black hair is crossed to a rabbit with short, white hair. All the offspring have long, black hair. What are the genotypes of the parents? A) LLBB x bb В) LIBЬ * LIBЬ С) LIBЬ * 1ьЬ D) LIЬЬ x 1ВЬ E) Impossible to determine from the information given 1 2-7 A couple has four children. What is the probability that they have four boys? A) 1/2 B) 14 C) 1/8 D) 1/16 E) 1/32 2-8 Humans have a gene, T, that is involved in muscle formation of the tongue. Individuals homozygous for one allele can roll their tongues, while individuals homozygous for the other allele cannot. If both parents can roll their tongues, but their child cannot, what can be said about the mode of inheritance? A) Tongue rolling is dominant. B) Tongue rolling is recessive. C) The parents were both homozygous, but the child was heterozygous. D) Tongue rolling is dominant, and both parents were heterozygous (Tt). E) Tongue rolling is recessive, and both parents were heterozygous (T) 2-9 In the accompanying figure, the chance that individual III-5 is a heterozygous carier is 3 5 5 8 9 10 1 13 14 15 IV " י" 15 8 11 12 13 14 A) 0% B) 25% C) 50% D) 75% E) 100% 2-9 What is the probability of rolling two six-sided dice and obtaining two 4s? A) 1/6 B) 1/3 C) 1/36 D) 1/9 E) 1/12 2-10 In pet rabbits, brown coat color is autosomal recessive to black coat color. A black female rabbit gives birth to 8 black-coated and 7 brown-coated baby rabbits. What can be deduced about the genotype of the baby rabbits' father?
