Question

You are a geneticist who is analyzing someone’s sex chromosome. It shows as XO. Which of the following disease or disorder does he/she have?
A. Hemophilia

B. Trisomy 21 or Downs Syndrome

C. Edwards Syndrome

D. Klinefelter’s Syndrome

Answer 1

Answer:

I'm not quit sure about this but I'm sure its hemophilia. Yes I'm a middles schooler who is answering a high schooler's question but in my biology class i do high school things here and there.

Explanation:

I'm sure it is hemophilia because 1. a father only passes one of his sex chromosomes which is either x or y (X for girl and Y for boy). 2. the new born can get, from the mother, either an x chromosome with the hemophilia or the other x with the normal blood clotting gene. I hope this helps and if not I am sorry
