Aphenotypically 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 (complete), explain how the abnormal chromosome was formed. in your answer, explain where the crossover occurred (i. e., between which two genes). also, give any other products that might have been formed as a result of the crossover you described. assume that crossing over does not occur at the centromere.
