Solution

The correct option is D 150
In pea plant, yellow seed color is dominant over green and round seed shape is dominant over wrinkled shape. A cross between yellow round (YYRR) and green wrinkled (yyrr) pea plant gives all yellow round (YyRr) plants in F $_{1}$ generation. Selfing of yellow round (YyRr) plants produce F $_{2}$ generation with 9 yellow round (YYRR) : 3 yellow wrinkled : 3 green round : 1 green wrinkled plants. Thus, out of a population of 800 individuals in F $_{2}$ $ generation number of yellow and wrinkled seeded plants is 3/16 x 800 = 150. Thus, the correct answer is option D.
