Question

Colorblindness is a sex-linked recessive trait. If B=normal and b=colorblind, what would be the genotype of a carrier female? Question 2 options: XbY XBXb XBYb XBXB

Answer 1

Answer:

XBXb

Explanation:

Because it is a female, you have to have X and X. You cant have X and Y. That eliminates the first and third answer.

Because she is a carrier, we have to use B and b, because only people that actually are color blind have B and B.

So, the answer you have left is XBXb

Hope this helps
