Question

since an xo female can survive but an oy male cannot, what can we conclude about the genetic information in the x and y chromosomes?
a) yy males can survive
b) females need the y chromosome to survive
c) xx females are healthier than xo females
d) males need at least one x chromosome to survive

Explanation:

The fact that an XO female can survive while an OY male cannot implies that the Y - chromosome alone does not carry sufficient genetic information for survival, and males require at least one X - chromosome for survival. There is no information to support options A, B, or C.

Answer:

D. Males need at least one X chromosome to survive
