As discussed in the experiment of Figure 19.9, the presence of a transposon can create a mutable site or locus that is subject to frequent chromosome breakage. Why do you think a transposon creates a mutable site If chromosome breakage occurs, do you think the transposon has moved somewhere else How would you experimentally determine if it has

Starting material: The plant contributing the female gamete was homozygous for a chromosome carrying c sh Wx. The male pollen of the corn plant was homozygous for a chromosome in which the Ds element had moved into the C gene: CDsC Sh wx.
