Polytene chromosome map and inversion polymorphism in Drosophila mediopunctata.
Drosophila mediopunctata belongs to the tripunctata group, and is one of the commonest Drosophila species collected in some places in Brazil, especially in the winter. A standard map of the polytene chromosomes is presented. The breakpoints of the naturally occurring chromosomal rearrangements are marked on the map. The distribution of breaking points through the chromosomes of D. mediopunctata...
متن کاملRecombination load in a chromosomal inversion polymorphism of Drosophila subobscura.
Chromosomal inversions suppress recombination in heterokaryotypes and may help to maintain positive epistatic interactions among groups of alleles at loci contained in the inversion. Here I evaluate the protective effect of inversions on recombination when different chromosomal segments, or even the whole chromosome O of Drosophila subobscura, can be effectively prevented from undergoing recomb...
متن کاملChromosomal Inversion Polymorphism in Natural Populations of Drosophila ruberrima
Shu Fang, Fei-Jann Lin and Hwei-yu Chang (1998) Chromosomal inversion polymorphism in natural populations of Drosophila ruberrima. Zoological Studies 37(4): 309-321. The standard map of the giant polytene chromosome of Drosophila ruberrima, one of the members of the immigrans species subgroup of the immigrans species group, is constructed according to the primitive gene arrangement or standard ...
متن کاملChromosomal localization of microsatellite loci in Drosophila mediopunctata
Drosophila mediopunctata has been used as a model organism for genetics and evolutionary studies in the last three decades. A linkage map with 48 microsatellite loci recently published for this species showed five syntenic groups, which had their homology determined to Drosophila melanogaster chromosomes. Then, by inference, each of the groups was associated with one of the five major chromosom...
متن کاملCHROMOSOMAL POLYMORPHISM IN DROSOPHILA EURONOTUSl
TUDY of the naturally occurring polymorphism found in the banded polytene Schromosomes of Diptera has yielded a great deal of information on the genetic structure of natu -a1 populations, and also in some instances has indicated the pattern of evolut .onary change which has occurred during species formation. Outstanding examples of studies of the latter sort are those in the Drosophila obscura ...
