    Beta hexoaminidase is made up of alpha and beta subunits,Tay Sachs results from mutation in alpha subunit while Sandhoff from alpha subunit,if the carrier of Tay sachs disease marries a carrier of Sandhoff disease,what is probability that their first child will have either disease?
    A 0%B 12.5%C 25%D 50%E 100%

    I think there is some formula for detecting probability,other than the explanation that all of us know,from that i would say my answer is,25%,C

    If somebody knows better explanation plz add.i has plenty of these kinds of Q at nb

    Since both are autosomal recessive they would normally be zero percent but since they both are defects in hexoasminidase(same gene but Sandhoff is both Hexosaminidase A and B) I would say 25% as well.
