Question

1.Describe the rearrangement in chromosomes A-C. indicate the specific markers genes flanking the crossover/breakage points (e.g., a translocation with breakpoints between markers X and Z).

2.Chromosome rearrangements can be caused by crossing over between repetitive DNA sequences.

Draw a picture similar to Figure showing how crossovers between repetitive sequences could have produced chromosome rearrangement A.

indicate the location and orientation of the repetitive DNA segments relative to the marker genes.

Shown below is the genetic map of the wild-type C. elegans chromosome Ill indicating the positions of
several marker genes and three chromosome rearrangements (A-C).
