The correct option is D.
Y chromosome analysis is a DNA technique that is used to research the paternal line. Females have two X chromosomes while males have one X chromosome and one Y chromosome. Offspring usually inherit one chromosome from the father and one from the mother. Sons that belong to one man usually have the same Y chromosome.Thus, the Y chromosome analysis is used to determine if the males in the family comes from the same father or paternal line.
