Recombination 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 کاملHomosequential Sympatric Hawaiian Drosophila: Drosophila Heteroneura and Drosophila Silvestris
According to Loiselle and Barlo~ (1978), "Lekking is the temporary synchronus aggregation of sexually active males for reproduction." It is a type of communal display. Theoretically, males displaying communally are more conspicuous and have a better chance of encountering females. Until recently, most of the research on lek behavior has been done on birds, especially grouse (Tetraonidae) and ma...

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 کاملSexual selection in Drosophila silvestris of Hawaii.
Previous discovery that Drosophila melanogaster females tend to discriminate in mating against phenotypes of earliest courting males prompted a study of the Hawaiian species D. silvestris. Tibial bristle variation in males from opposite coasts of the island of Hawaii functions in courtship, and the possibility that females can distinguish males differing in the tibial trait is explored. Mating ...
