Colorblindness Probability Help!

Post by kaylagh » Sun Sep 07, 2014 6:07 am

The incidence of an XXY karyotype is about 1 in every 1000 male births, the extra X chromosome coming either from the mother's egg or the father's sperm by nondisjunction during meiosis. Suppose the baby's father has red-green colorblindness. Would you predict that the baby boy with an XXY karyotype would also be colorblind, and why? Under what conditions could he be colorblind, like his father?


Please help! Thank you :)
