In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r).
Mention the phenotype and genotype ratios of the offspring in F₂ generation.

Solution

To find the phenotype and genotype ratios of the offspring in F₂ generation,
Punnett square :
R r
R RR Rr
r Rr rr
Hence the offsprings in the F₂ generation :
RR (round)
Rr (round)
rR (round)
rr (wrinkled)
Therefore, the phenotype ratio is 3:1, and the genotype ratio is 1:2:1 of the offspring in the F₂ generation.
