In pea plants, yellow seed color is dominant and green seed color is recessive. What will the generations look like? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed. Check all that apply.
Answer
A
The P generation has all yellow seeds.
B
The P generation has all green seeds.
C
The P generation has yellow and green seeds.
D
The F1 generation has yellow and green seeds.
E
The F1 generation has all yellow seeds.
F
The F2 generation has all green seeds.
G
The F2 generation has yellow and green seeds.
Explanation
The P generation consists of two true-breeding parents with opposite traits: one has yellow seeds and the other has green seeds, so the parents together have both colors (C). Crossing them produces F1 plants that all show the dominant yellow trait (E). When the F1 plants are crossed, the recessive green trait reappears in the F2 generation, so it has both yellow and green seeds (G).
