If the F1 generation allows for self-pollination, what will be the genotypic ratio of the offspring?
-
1 : 2 : 1
- 2 : 2
- 3 : 1
- 2 : 1 : 1
The correct answer is: A
Explanation
Self-pollination is the transfer of pollen grains from the anther to the stigma of the same flower. If the F1 generation self-pollinates, the genotypic ratio of the offspring will depend on the genotype of the F1 generation. The genotypic ratio is 1:2:1
(See diagram above)
