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.
The hormone produced by the placenta that stimulates the ovaries to continue producing estrogen and progesterone is called the follicle stimulating hormone. This hormone stimulates the ovarian follicle allowing the egg to grow thus producing continuous supply of estrogen and progesterone.
