Solution

The correct option is D P generation
A genetic cross between parents that differ in the alleles they possess for one particular gene, one parent having two dominant alleles and the other two recessives. In the case of a monohybrid cross, only the parent generation is always completely homozygous.
So, the correct option is 'P generation'.
