Question

22. The tall allele, T, is dominant to the short allele, t, in Mendel's pea plants. You examine a pea plant that exhibits the tall phenotype. What is its genotype? A. Tt B. TT C. tt D. A and B are both possible. 23. In pea plants, round (R) is dominant to wrinkled (r). A heterozygous female is crossed with a wrinkled male. What is the probability to get a wrinkled seed? A. 100% B. 75% C. 50% D. 25% 24. A pea plant homozygous for the trait of round seeds is crossed with a pea plant that is homozygous for the trait of wrinkled seeds. The first generation produces seeds that are all round. What percent of the second-generation plants will have round seeds when the F1 generation is self-fertilized? A. 100% B. 75% C. 50% D. 25% 25. In rabbits, brown fur color is dominant to white fur color. If a homozygous brown rabbit is mated with a white rabbit and 8 offspring are produced, how many would be expected to be white? A. 0 B. 3 C. 6 D. 8 26. Imagine two heterozygous parents, each with a Bb genotype where brown eyes (B) are dominant to blue eyes (b). The phenotypic ratio for brown:blue eyes in their children is: A. 3:1 B. 1:0 C. 1:2:1 D. 4:0 27. In squirrels, the gene for gray fur (G) is dominant over the gene for black fur (g). If 50% of a large litter of squirrels are gray, the parental cross that produced this litter was most likely: A. GG x GG B. Gg x gg C. Gg x Gg D. GG x G 28. In humans, presume brown eyes (B) are dominant over blue eyes (b). A brown-eyed woman has a blue-eyed child. The mother's genotype would be: A. bb B. Bb C. BB 29. If an organism shows a recessive phenotype, such as short pea plants, it can be: A. either TT or Tt B. either Tt or tt C. only tt D. both TT & tt
