Consider a population that is polymorphic for a chromosomal
inversion. The standard arrangement of five loci on this chromosome
is A-B-C-D-E, and the inverted arrangement is
A-(E-D-C-B). The genetic distance between all adjacent
loci is 5cM. What is the expected proportion of progeny with
genotypes BbDd or bbdd from a cross between a
male with genotype a-b-c-d-e/a-b-c-d-e and a female with
the following genotype:

a) A-B-C-D-E/a-b-c-d-e

b) A-(E-D-C-B)/a-b-c-d-e

c) A-E-D-C-B/a-e-d-c-b
