A diploid plant has red flowers, heavy seeds and large leaves. The plant is a heterozygous for the following three genes:
flower color (gene “F”),
seed weight (gene “S”),
and leaf size (gene “L”).
This plant is testcrossed to a plant, which has white flowers, light seeds, and small leaves, the progeny of the testcross is as follows:
|
222 |
Red, heavy, large |
|
228 |
White, light, small |
|
224 |
Red, heavy, small |
|
226 |
White, light, large |
|
24 |
Red, light, large |
|
26 |
White, heavy, small |
|
25 |
White, heavy, large |
|
25 |
Red, light, small |
Based on this results, which of the following statement is correct?
Question 9 options:
