Question

16. A pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. Round pea shape is dominant to wrinkled, and yellow pea color is dominant to green. Members of the resulting F1 generation are then crossed to produce an F2 generation, as shown in the figure. On average, what fraction of the F2 generation will display both dominant traits?

SnapAndSolve AI · Accepted Answer

Answer: In the F2 generation, the fraction that will display both dominant traits (round and yellow) can be determined by analyzing the Punnett square. The dominant traits are represented by R (round) and Y (yellow). The genotypes that show both dominant traits are RY. In a typical dihybrid cross, the phenotypic ratio is 9:3:3:1, where 9 out of 16 offspring will display both dominant traits. Therefore, the fraction is 9/16.
