Explanation: Corticotropin-releasing hormone and vasopressin are responsible for the release of adrenocorticotropic hormone (ACTH), which in result have effect on the release of hormone from adrenal cortex.
Cortisol is the hormone produce in response of ACTH effect on adrenal cortex. In the condition of stress; metabolic effects, nervous system effects are produced.
Corticotrophs from anterior pituitary gland secretes adrenocorticotropic hormone under stress conditions. ACTH stimulates the cortex of the adrenal gland to secrete glucocorticoids. Cortisol is the main glucocorticoid secreted by the adrenal cortex. This hormone triggers the break down of fats and proteins as well as stimulate gluconeogenesis. All these physiological responses prepare the body to combat stress or emergency conditions.
"Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.
The answer is 25%. The
other 75% will have dominant phenotype. However,
in the dominant phenotype, 25% have a homozygous dominant genotype, while the remaining
50% have a heterozygous genotype. Find attached a punnet square that will
clearly illustrate this;
