Since pollen is a gamete, that means that it will get half of the genetic information required to make the corn plant. (Pollen is like sperm, that will find a stigma to then proceed to pollinate the flower and make a plant, after a few processes.) All possible genetic combinations in pollen would be... ST, St, sT, st. I used a punnett square to determine the possible combinations. And attached to this I have a poorly drawn sketch of what I did. I am new here so I don't know if you have a question ask me or something.

Explanation:
Answer:
basically a segment of DNA
Answer:
DNA is consist of two strands that are coiled together to form a double helix structure in which both the strands are anti-parallel. The direction of one strand is from 5' to 3' and the other has 3' to 5'.
DNA is made up of nucleotide, phosphate group and deoxyribose sugar. The two anti-parallel strands on DNA are composed of nucleotide and bonded with hydrogen bond. There are four nitrogenous bases present in each nucleotide e adenine (A), guanine (G), Thymine (T) and cytosine (C). Where A and T are bonded with double hydrogen bond and G and C are bonded with triple hydrogen bond present complementary to each other in both the strands.
sugar -phophate group forms the backbone of the DNA.
