Transmission by heterozygous females is reduced by nonrandom disjunction of heteromorphic dyads resulting from exchange between the compound and a normal homologue, but it is high if recombination is suppressed by homologous inversions. Transmission by heterozygous males is low.
recovered from female Recovered as a translocation involving the centric heterochromatin of both elements resulting in the replacement of one arm of C(2)EN with 3R3L.
