Analysis of B-genome chromosome introgression in interspecific hybrids of Brassica napus × B. carinata.

abstract：:Most species of the Drosophila genus and other Diptera are polymorphic for paracentric inversions. A common observation is that successful inversions are of intermediate size. We test here the hypothesis that the selected property is the recombination length of inversions, not their physical length. If so, physical le...
