Answer:

Negative feedback loop

Explanation:

When the blood calcium level is low, the receptors of the parathyroid gland sense it and increase the production of cAMP. The increased cAMP levels stimulate the secretion and release of parathyroid hormone from the parathyroid gland into the blood.

The increased parathyroid hormone levels stimulate the number and activity of osteoclasts and speed up the process of bone resorption resulting in the release of calcium ions from bone into the blood to raise the blood calcium levels.

Here, the response (increased blood calcium level) reverse the stimulate and hence, the process is under the regulation of negative feedback loop .

Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.

To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.
