Answer:
Calcium
Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
Complete question:
Punnet squares for genes found in sex chromosomes are unique in that the pattern of inheritance of these traits is gender-specific. For example, examine the following Punnet square for color blindness, a trait found in the X chromosome (Y chromosome carry only a few genes but they do not possess enough coded information to initiate the development of the male).
Xcb represents the X chromosome carrying the color blindness trait. The allele for color blindness is recessive to the normal form of the gene (X).
Punnet square:
Mother
Xcb X
Father X X Xcb X X
Y Xcb Y X Y
Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype?
Answer:
<em>YES. Male and female offspring </em><u><em>will have the same likelihood</em></u><em> of carrying the colorblindness trait in their genotype. </em>
