The offspring of AA bb × aa BB is crossed with, aabb. The genotypic ratio of progeny will be
The cross is made between AAbb to aaBB. The progeny formed shows the genotype AaBb. This progeny is crossed with aabb. The genotypes of the progeny are 4 AaBb, 4Aabb, 4aaBb, 4aabb. The genotypic ratio is 1:1:1:1.
So, the correct option is ‘1:1:1:1’.
