Q3. (Section 13.3) In the following figures, genes A and B are on the human X chromosome (blue) and both are subject to X inactivation, whiles genes C and D are on chromosome 17 (an autosome; red). F and S refer to alleles encoding fast and slow-migrating forms of the coresponding proteins that can be discriminated by gel electrophoresis. For women 2 and 3 in the figures, indicate all the possible forms of the four proteins that could be expressed in clones made from different individual somatic cells that had a Barr body. (As an example, woman 1 could express AF, BF, CF, CS, DE, and D'S proteins in some clones and AS, BS, CF, CS, DF, and DS proteins in other clones.) Note that woman 2 is a heterozygous for a deletion of the XIC and woman 3 is a heterozygous for a reciprocal translocation in which parts of the X chromosome and chromosome 17 have exchanged places. Woman 1 XIC Woman 2 BF of XIC DF BF CF AS BS CS XIC DS AS BS CS DS Woman 3 XIC AF DS CS BF AS BS XIC DF
