State the expected ratio of genotype yy and yy in F2 progenies

What is the genotypic ratio of the progenies?

1:1:1:1 genotypic ratio of progenies can be obtained if the plants being crossed have the genotypes.

What is the expected genotypic ratio in the F2 generation?

The normal phenotypic ratio in F2 generation is 3:1 and the genotypic ratio is 1:2:1.

What are the genotypes of the F2 pregnancy?

F2 tall red plants will have 4 genotypes, i.e. homozygous tall homozygous red (TTRR), homozygous tall heterozygous red (TTRr), heterozygous tall and homozygous red (TtRR), and heterozygous tall and heterozygous red (TtRr) will be in the ratio of 1:2:2:4.

What is the genotype ratio of BB and BB in F2 generation?

(c) The ratio of the genotypes BB and Bb in the F2 generation would be 1(BB) : 2 (Bb).
