Genetic linkage mapping
Genetic linkage mapping for a large number of families identifies 4%
recombination between the genes for Rh blood type and elliptocytosis. At
the Rh locus, alleles R and r control Rh+ and Rh- blood types. Allele E
producing elliptocytosis is dominant to the wild-type recessive allele
e. Tom and Terri each have elliptocytosis, and each is Rh+. Tom's mother
has elliptocytosis and is Rh- while his father is healthy and has Rh+.
Terri's father is Rh+ and has elliptocytosis; Terri's mother is Rh- and
is healthy.
What is the probability that the first child of Tom and Terri will be Rh- and have elliptocytosis?
