Question

The possibility that Mongolian ruler Genghis Khan spread an unusual chromosome to nearly 16 million men living today resulted from studies of ________.
A) proteomics
B) plasmids
C) the X chromosome
D) the Y chromosome

Answer 1

Answer:

D. the Y chromosome

Explanation:

Men have an X and a Y chromosome while women have two X chromosomes. Since the unusual chromosome was spread to nearly 16 million men, it was most likely a Y-linked trait as only men inherit a Y chromosome. If it was an X-linked trait, both men and women would be able to get it since both inherit X chromosomes.

Hope that helps.
