The white color of the corolla in phlox dominates over pink. A plant with a white corolla is crossed with a plant that has a pink color. 96 hybrid plants were obtained, of which 51 are white and 45 are pink. 1) What genotypes do the parent plants have? 2) How many types of gametes can a plant with a white corolla form? 3) How many types of gametes can a plant with a pink corolla form? 4) What phenotype ratio can be expected in the F2 generation from crossing between F1 hybrid plants with white flowers?

Solution.
A is a white color, a is a pink color. The genotype of one plant A .. is white, the second aa is pink.
Since in the first generation there is a splitting of 1: 1 (51:45), the genotype of the first plant is Aa.
Let’s make a crossing scheme.
Answers:
1. Aa and aa.
2. 2
3.1
4. 3 with a white whisk: 1 with a pink whisk.
