Answer:

Sustainable use of the environment

Explanation:

A young boy has been found, and police are trying to locate his family. They take a DNA sample from him and begin collecting DNA

GaryK [48]

Answer:

The correct answer would be Y-chromosome analysis.

Y-chromosome analysis is technique used to search the parental line of a boy on his father's side.

Gender of a person is determined by $23^{rd}$ chromosome in humans. XX is present in females and XY is present in males.

Mother always passes X chromosome to her progeny but father passes both X and Y chromosomes. If X is passed from the father then the offspring will be a girl and if Y is passed from the father then the offspring will be the son.

The sons (F₂) of this son (F₁) will also bear the same Y chromosome as that of grand father (P).

Thus, Y chromosome always passes from father to son and hence, Y-chromosome analysis can help in identification of father of this young boy.
