Tay-sachs disease (ts) is a fatal, recessive genetic disorder in which harmful quantities of a fatty waste substance accumulate in the brain, slowly progressing to death by age five. ts carrier status is common 7. g individuals of eastern european jewish descent, with a carrier frequency of about 1 in 27. in the general population, on the other hand, the carrier rate is about 1 in 250.
a) give the probability that both parents are carriers in each of the following situations:
(i) both mom and dad are of european jewish descent.
(ii) mom is of european jewish descent, but dad isn't.
(iii) neither mom nor dad is of european jewish descent. if both parents are carriers, the probability is 0.25 that their child has ts. otherwise, the probability is zero.
a. draw a probability tree diagram for the children of parents who are both of european jewish descent. then, use your tree diagram to find the probability that a child has ts given that both parents are of european jewish descent.
b. what is the probability that a child has ts given that neither parent is of european jewish descent?
