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?


St, sT

Ss, Tt, ST, st

ST, st

ST, sT, St, st

Verified Answer :

The last answer is what I am thinking is correct

Answer:

Option D, ST, St, sT, st

Explanation:

Genotype of corn plant is SsTt

If we are required to determine the genetic combinations that could be present in a single grain of pollen produced by the plant would be equivalent to the cross between the two traits i.e

Ss x Tt

The resulting genetic combinations would be a pair of allele having one allele of each trait.

Hence, the possible genetic combinations are -

ST, St, sT, st

Hence, option D is correct
