Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose f
Anettt [7]

Answer:

Man: Bb

Man’s mother: bb

Woman:Bb

Woman’s father: bb

Explanation:

Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.

Anuta_ua [19.1K]

Her hypothalamus will secrete vasopressin. If her dehydration becomes severe, her secretion of vasopressin will increase.

<h3>What is vasopressin?</h3>
  • The posterior pituitary gland releases the peptide hormone vasopressin, also known as antidiuretic hormone.
  • Which is produced by the supraoptic and paraventricular nuclei of the hypothalamus (neurohypophysis).
  • It primarily functions as an anti-diuretic in the kidney, where it causes the body to reabsorb water by acting on the distal region of the nephron when it is dehydrated.
  • The AVP gene for it is found on human chromosome 20.
  • Vasopressin has an antidiuretic effect; it reduces the volume of urine by raising the collecting tube's water permeability.
  • It attaches to the G protein-coupled V2 receptor, which in turn starts a signaling cascade through the PKA.
  • Aquaporin 2 (a transmembrane pore) is produced as a result, and it is then transported to the apical/urinary membrane.
