Answer:

Option C or 3, i.e Ab and aB is correct

Explanation:

First copy of allele is AB

Second copy of allele is ab

The allele pair AB will segregate into genes A and B

The allele pair ab will segregate into genes a and b

The recombinant genotype will consist of one gene from each allele pair

Thus, if first allele pair give A gene the second allele pair will given b gene, so the genotype would be Ab

Likewise, if if first allele pair give B gene the second allele pair will given a gene, so the genotype would be aB

Option C or 3, i.e Ab and aB is correct

What is the role of renin in the secretion of aldosterone?
Gelneren [198K]

Answer:

Explanation:

Aldosterone is a hormone which is produced by the adrenal glands which are present above the kidneys. The role of aldosterone is to regulate the blood pressure. It causes the reabsorption of water and salts into the bloodstream during the kidney filteration process. Hence, maintains the blood volume, restors blood pressure and salt level.

Renin is an enzyme. It facilitates chemical reactions which stimulates the synthesis of angiotension II, it directs the synthesis of aldosterone.
