As a genetic counselor, you may face some ethical dilemmas. Imagine that a couple came to your office to discuss potential color blindness in their children.  The man is not color blind, but his wife is.  They already have one daughter that is color blind and want to know the probability of future children having the disorder.  First, you will need to explain to the couple the difference between sex chromosomes and autosomal chromosomes and that color blindness is caused by a recessive mutation in a gene found on the X chromosome.  Once they understand this, you can then explain to them the probability of other offspring having the disorder.  What is the dilemma in this case and why might you need to suggest to the couple that they see a marriage counselor?
