The diagram below shows the chromosomes of a plant that is heterozygous at six loci as well as for a reciprocal translocation involving the chromosomes that carry these loci. This plant is crossed to a plant with normal chromosomes that is homozygous recessive at all loci,and the progeny was comprised of about 250 individuals,half of them phenotypically ABDEFG and half abdefg.This result suggests that:
A)multiple crossovers occurred.
B)no crossovers occurred.
C)segregation was always adjacent.
D)segregation was always alternate.
E)the six loci are unlinked.
