Rr and rr in the ratio of 1:1

Explanation:

If allele for smooth seed is Dominant over the allele for wrinkled seeds, and they are crossed 50 per-cent of the progeny will be heterozygous dominant and 50 per-cent will be homozygous recessive.

Rr X rr

Rr Rr rr rr F1 generation.

r r

R rR rr

r Rr rr

From Punnet square it will be 50 per-cent chance each of rr and Rr.
