[Medcine/genetics] Ca^`n giu'p Ba.ch ta.ng & nhie^~m sa('c 11

["Toan" <toan@usa.net>]

You can even write English, but Viet is prefered because I need to explain
this in Viet.
I need help explaining Ocularcutaneous Albinism and chromosome 11& the
implications for a couple carrying a baby. The mother has full blown OCA,
the father has not had any DNA test, but we can assume the probabilities.
