Evolutionary cytogenetics of the Drosophila buzzatii species complex.

摘要: The salivary gland chromosomes of 10 species in the Drosophila mulleri subgroup (repleta group) have been re-analysed. These include eight members South American buzzatii and martensis clusters, previously ascribed to complex, two Caribbean D. stalkeri richardsoni, comprising complex. chief results can be summarized as follows. Inversion 3a is not present cluster. Hence, there no cytological link between this cluster, or rest Accordingly, a new established with clusters. richardsoni share at least inversions all produce hybrids interspecific crosses many them. This indicates close phylogenetic relationship. Therefore, are incorporated cluster within newly erected A tree illustrating chromosomal evolution complex presented previous information concerning its reviewed.
