probability of 2 carriers getting married - 1/30 times 1/30
praobability that dad will give the affected gene 1/2
probability that mom will give the affected gene 1/2
so the probability of having a child with tay sachs... 1/30 times 1/30 times 1/2 times 1/2
= 1/3600

can we do like
1/30 times 1/30
as the chances of two carriers having an affected child is 1 in 4
so 1/30*1/30*1/4=1/3600
jus asking if this concept is rite
