In tomatoes, the gene that determines the red color of the fruit is dominant over the gene for the yellow color.

In tomatoes, the gene that determines the red color of the fruit is dominant over the gene for the yellow color. 3021 tomato bushes obtained from hybrid seeds had a yellow color, and 9114 – red. Determine the genotype of the parents and offspring

Given:
A-red coloring
a-yellow color
Red -9114
Yellow-3021
Find: genotype F1 and P-?
Decision:
The ratio of red hybrids to yellow = 9114: 3021 = 3: 1 this means that the type of inheritance is complete dominance, which means that the parents are heterozygotes
R: ♀️Aa * ♂️Aa
G: A a * A a
F1: AA (25% – Red) 1 hybrid
Aa (50% – red) 2 hybrids
aa (25% – yellow) 1 hybrid
The ratio of reds to yellows is 3: 1. All right
