If a corn plant has a genotype sstt, what are the possible genetic combinations that could be present in a single grain of pollen produced by the plant?

ss, tt, st, st
ss, tt, st, st
st, st
st, st, st

The correct answer would be St, st.

Explanation:

A dihybrid cross is a cross between individuals that involves two pairs of contrasting traits. According to given corn plant genotype which is Sstt shows that it has one hetrozygous condition (Ss) for trait that mark by S or s allele and homozygous condition (tt) for trait mark by t allele.

Gametes or pollen carry only one allele for every trait dominant or recessive. Therefore, only one allele will be present in pollen either S or s for heterozygous trait while homozygous has only one allele.

Possible genetic combination in a single grain can be St and st.

Thus, the correct answer is St and st.
