Exercise 14
A phenotypically abnormal individual has a phenotypically normal father with an inversion on one copy of chromosome 7 and a normal mother without any changes in chromosome structure. The order of genes along chromosome 7 in the father is as follows:
R T D M centromere P U X Z C (normal chromosome 7)
R T D U P centromere M X Z C (inverted chromosome 7)
The phenotypically abnormal offspring has a chromosome 7 with the following order of genes:
R T D M centromere P U D T R
With a sketch, explain how this chromosome was formed. In your answer, explain where the crossover occurred (i.e., between which two genes).
