by calculation... there is 100% chance of having disease...
but guys..do u think that if a child is having tay sachs disease, will grow to adult to hv his own child!!!
if they r suffering from disease...means having both mutated allele...most probably they cant live for more then 5 yrs???:notsure:
Answer is "D" 100% probability since Taysach is Autosomal recessive ... And both parents are affected.
-If one of the parents is affected & the other is normal, the answer will be zero but all children will be carriers.
-If both are carriers, the answer will be 25%. If one of parent is carrier and the other is affected.
-If one is carrier & other parent is affected, the answer will be 50% risk with teh otehr 50% carrier children.
