Abstract

Background: In a number of organisms sex-biased genes are non-randomly distributed between autosomes and the shared sex chromosome X (or Z). Studies on Anopheles gambiae have produced conflicting results regarding the underrepresentation of male-biased genes on the X chromosome and it is unclear to ...

Abstract

For >60 years, evolutionary cytogeneticists have been using naturally occurring chromosomal inversions to infer phylogenetic histories, especially in insects with polytene chromosomes. The validity of this method is predicated on the assumption that inversions arise only once in the history of a ...

Abstract

Haldane's rule states that species hybrids of the XY sex are preferentially sterile or inviable. In all taxa known to obey this rule, the Y is inert and X-linked genes show full expression in XY individuals. Until recently, all theories of Haldane's rule depended on this hemizygosity. A test of...

Abstract

The cytogenetics of the Neocellia and Myzomia groups of anopheline mosquitoes is discussed, with particular reference to chromosome inversions.

Abstract

At the chromosomal level, heterochromatin differentiation resulting in karyotypic evolution provides a useful tool for cytotaxonomy of many groups of animals including the Diptera. Detectable differences in the amount and distribution of heterochromatin have been observed in several groups of...

Abstract

Chromosome number and morphology in mosquitoes is remarkably uniform: virtually all mosquitoes have a diploid chromosome number of 6 (2N = 6), and their chromosomes are invariably metacentric or submetracentric. Numerical changes obviously have not been important in mosquito chromosomal evolution,...

Abstract

Cladistic methodology is discussed in the context of mosquito chromosome inversions, and the available data within Anopheles (Cellia) is reinterpreted. Within the Myzomyia Series, a sister group relationship is corroborated between the Wellcomei group and the clade Funestus group + Rivulorum group, ...

Abstract

Polytene chromosomes from the nuclei of the Malpighian tubules of a laboratory strain of C. quinquefasciatus were stained and observed by light microscopy. The chromosomal arms 1R and 3L did not exhibit heterozygous puffing, whereas the rest of the arms (1L, 2L and 3R) showed puffs in 38 of 125...

Abstract

Evolutionary and diagnostic questions concerning the A. gambiae complex have been approached by exploring the utility of rDNA sequences, which have numerous advantages over previous techniques. These advantages include a high copy number, and highly conserved as well as highly variable regions that ...

Abstract

Ovarian polytene chromosomes from 8 populations of Anopheles quadrimaculatus in the south-eastern USA were observed for chromosomal polymorphisms. Two sibling species, A and B, each with intraspecific inversions, were distinguished. Species A correlated with the previously published standard maps...
