Question

Sperm cells carrying the Y chromosome will
A always result in the conception of a female baby
B will result in the conception of twins more often than those carrying an X chromosome
C typically result in children with brown eyes
D usually carry less genetic material than those carrying the X chromosome do

I believe the correct answer is D

Answer 1

You are right. Since the Y chromosome has fewer genes than the X chromosome, the Y-bearing sperm will have less genetic material than the X-bearing sperm.

I hope this helps. Thanks for asking.
