PKU is an inherited disease caused by a recessive allele. If a woman and her husband, who are both
carriers (heterozygotes) for the disorder, have three children, what is the probability of each of
the following?
a) All three children are of normal phenotype.
b) All three children have the disease.
c) Any 2 of the three children have the normal phenotype.
what is the probability that a couple (both heterozygous for the same recessive mutation) will have two children with the disease if the couple plans to have four children in total?
For an X-linked recessive disease where the father is unaffected:
a) An affected father cannot pass the disease mutation on to his daughters.
b) all affected mothers will be heterozygous at the trait locus.
c) a homozygous affected mother will have only affected male offspring.
d) a homozygous affected mother will have only affected female offspring.
e) if a homozygous affected mother mates with an unaffected father, 75% (on average) of the male offspring will be affected.
