Answer:

The correct answer would be option D.

Explanation:

Pollen of a plant is a gamete, that contains half of the alleles are required to produce the plant. Pollen fuse with stigma and complete the required alleles or genetic information.

Possible combinations in pollen would be one allele from each trait in every form either dominant or recessive. So ST, St, sT, st. would be the correct possible genetic combination present in a single grain.

Thus, the correct answer is option D.

Answer:

Option D

Explanation:

There are two different traits represented by the term "SsTt". Where "S" is the allele for a dominant trait 1 and "s" is the allele for a recessive trait 1.  Like wise "T" is the allele for a dominant trait 2 and "t" is the allele for recessive trait 2.

In a genetic combination , both the  allels of both the traits will pair up with each other one by one.

i.e "T" will pair up with both "S" and "s" to form "TS" and "Ts" gametes

Similarly "t"will pair up with both "S" and "s" to form "tS" and "ts" gametes

Hence, option D is correct
