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

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
