A couple is about to have a child. They are concerned about the child because of two traits caused by genes on the SAME chromosome: Tay Sachs, an autosomal recessive neurodegenerative disease, and Polydactyly, a dominant extra finger trait. The two genes are 20 map units apart. The mother has Tay Sachs but does not have polydactyly. The father is a carrier of Tay Sachs, and has polydactyly (he is heterozygous): the two dominant alleles for these phenotypes are on one chromosome, and the two recessive on the other.
