Question

Which test would be useful for determining if multiple male samples are related?

a.mtDNA  b. RFLP c. y-chromosome  d. none of these

Answer 1

A DNA test would fit this situation best. If the male samples are related, it will show up in the DNA test results.

Answer 2

The correct answer would be option c. Y chromosome.

In humans, the males contain one X chromosome and one Y chromosome. In contrast, females contain two X chromosomes.

Thus, DNA sampling of the Y chromosome would be best to determine if the two male samples are related or not.

In addition, mtDNA is often inherited from the mother and thus, it would not be a good option to determine the relationship between the male samples.
