|---|---|
| (a) True-breeding red-flower genotype | (i) Pink flower phenotype |
| (b) Heterozygous genotype | (ii) White flower phenotype |
| (c) Homozygous white-flower genotype | (iii) Red flower phenotype |
| (d) F2 generation phenotype ratio | (iv) 1:2:1 |
A
a-iii, b-i, c-ii, d-iv
B
a-ii, b-i, c-iii, d-iv
C
a-iii, b-ii, c-i, d-iv
D
a-iii, b-i, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
In the example of incomplete dominance with snapdragons, true-breeding red-flowered plants have the genotype RR, resulting in a red flower phenotype. The heterozygous genotype Rr leads to a pink flower phenotype, while the homozygous white-flower genotype rr corresponds to a white flower phenotype. The F2 generation exhibits a phenotype ratio of 1 red: 2 pink: 1 white, confirming the 1:2:1 ratio.
