In pea plants, Mendel found that the allele for smooth seeds (S) is dominant , while the allele for wrinkled seeds (s) is recessive. Which Punnett square shows crosses between plants heterozygous for smooth seeds and homozygous recessive for wrinkled seeds?
a.
s s
s ss ss
s ss ss
b.
S s
S SS Ss
s Ss ss

c. S s
s Ss ss
s Ss ss

d.
S S
S SS SS
s Ss Ss

C
Homozygus means the same. In this case, it is a recessive trait so there will be two little s.
Heterozygus means different. There is one S and one s.

when you cross them, you will have Ss ss Ss ss.

It is given in the question that the allele for smooth seeds (S) is dominant, while the allele for wrinkled seeds (s) is recessive.

What do you mean by Allele?

An Allele may be characterized as one or two or more alternate forms of any gene that is selected for studies.

Parents for heterozygous smooth seeds (Ss) are crossed with parents for purebred recessive wrinkled seeds (ss). The resulted offsprings are Ss, ss, Ss, and ss.

Therefore, the correct Punnett square which represents this condition is the third one (C).
