In an inversion heterozygote. one of its chromosomes shows the following linkage relationship:
In the homologous chromosome, there exists an inversion in the region
(1)What type of inversion is it
(2)Please draw a synaptic scheme(联会图)of these two chromosomes.
(3)If in the inverted chromosome region there is a lethal gene D at d locus, and in the normal(i.e., without inversion)chromosome there is another lethal gene F at f locus. How much of F1 individuals will be double(both at d and f loci) heterozygote when the inversion heterozygote self-crosses Why
