<h3>What is pollen grain?</h3>A seed plant's pollen is a collection of microspores that typically takes the form of a fine dust. Each pollen grain is a tiny body with a unique shape and structure that develops in seed-bearing plants' male structures before being carried by a variety of agents (such as wind, water, insects, etc.) to the female structures, where fertilization takes place.
The genotype in question is a mono-hybrid heterozygous characteristic.
The pollen grains having a genetic combination like ST, St, sT, and st as depicted in the image will result from a cross between the two genotypes.

Explanation:
When male and female comes to contact by initial connection between sex organs, the sperm (male gamete) enters through the vagina and gets fuses with an ova (egg- female gamete) which results in the process of fertilization (fusion of male and female gamete). This fertilized egg gets implanted to the Uterus (elastic bag like structure) which helps to the complete development of the foetus (baby).
