What hormone released by the highlighted structures inhibits the secretion of FSH only?
soldi70 [24.7K]

Inhibin inhibits the secretion of FSH only.

<h3>What is the role of inhibin?</h3>
  • Inhibin is a protein mainly produced by the gonads.
  • In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
  • It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
  • FSH itself induces the production of inhibin for negative feedback.
  • Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
  • Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.

You cross purple-flowered and white-flowered pea plants, and all offspring are purple. how come? select one:
Vaselesa [24]
To solve this problem on genetic dominance, we will need a punnet square.

Let's let P represent purple-flowered and p represent white-flowered.

We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.

       <u>P</u>     <u>P</u>
p|    Pp   Pp

p |   Pp   Pp

As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.

Since each flower has a dominant and recessive allele, they are heterozygous.

Therefore, the solution to this problem is D.
