Genetics

I saw this movie the other day and i've been thinking: why dont people get tested before they have children? I think that the answer too this question is because they dont know that there are deadly genetic disorders that can hurt their children. The one that stands out in my mind is ALD. This one comes from the mother. It only appears in boys from the age of 5 to 10. Most of them die with in two years of finding out they have it. Not knowing what this is can scear a person because they might not know what it is. This is a very rare disorder but its out there. I know that when i am ready to have kids i'm going to get checked out too see what i am at risk of giving my children. And of course there are other ones out there and they are dangerous also but this one kills the child early-on.
