144Chapter 4 •Eukaryote Chromosome Mapping by Recombinationchildren (who is Rh1 E) marries someone who isRh1e, and they have an Rh1 E child.a.Draw the pedigree of this whole family.b.Is the pedigree in agreement with the hypothesisthat the Rh1allele is dominant and Rh2is recessive?c.What is the mechanism of transmission of ellipto-cytosis?d.Could the genes governing the E and Rh pheno-types be on the same chromosome? If so, estimatethe map distance between them, and comment onyour result.17.From several crosses of the general typeA/A?B/B3a/a?b/bthe F1individuals of typeA/a?B/bwere testcrossed to a/a?b/b. The resultsare as follows:19.In the accompanying pedigree, the vertical linesstand for protan colorblindness, and the horizontallines stand for deutan colorblindness. These are sep-arate conditions causing different misperceptions ofcolors; each is determined by a separate gene.
