Chapter 12 Study Questions

  1. Three loci are linked in the order B-C-A. If the A-B map distance is 1 cM, and the B-C map distance is 0.6 cM, given the lines AaBbCc and aabbcc, what will be the frequency of Aabb genotypes among their progeny if one of the parents of the dihybrid had the genotypes AABBCC?
  2. Given the restriction digests and with the fragment sizes shown in the gel diagram, can you construct a map of this linear DNA molecule (Lambda DNA)?
