Chromosomal Evolution in Chiroptera
Chiroptera is the second largest order among mammals, with over 1300 species in 21 extant families. The group is extremely diverse in several aspects of its natural history, including dietary strategies, ecology, behavior and morphology. Bat genomes show ample chromosome diversity (from 2n = 14 to 62). As with other mammalian orders, Chiroptera is characterized by clades with low, moderate and ...
متن کاملChromosomal Evolution
The possibility that the Peromyscus maniculatus complex of deer mice arose via the process described as "centrifugal speciation" (Brown, 1957) has been discussed by Bowers et a l . , 1973, Lawlor, 1974, Baker et al., 1975, and Greenbaum et a l . , 1978. This study was designed to yield additional da ta on the cytogenetics of three species of this complex in order to evaluate the "centrifugal sp...
متن کاملChromosomal changes in vertebrate evolution.
The immense variety of karyotypes found in extant species is unmis takable evidence that the process of evolution is associated with karyo typic change. The question whether the chromosome changes are a cause or a consequence of speciation has been debated intensely for many years and, as is often the case with biological problems, there has been no unequivocal answer. Evolution operates alon...
متن کاملRearrangements and chromosomal evolution.
Comparisons of the genome sequences of related species suggests varying patterns of chromosomal rearrangements in different evolutionary lineages. In this review, I focus on the quantitative characterization of rearrangement processes and discuss specific inventories that have been compiled to date. Of particular interest are the statistical distribution of the lengths of inverted or locally tr...
متن کاملXenopus Cytogenetics and Chromosomal Evolution.
The genus Xenopus represents important model organisms in the field of developmental biology and chromosomal evolution. Developmental processes are tightly coupled with the analysis of gene function via genetic linkage and mapping. Cytogenetic techniques such as chromosome banding or FISH are essential tools for the determination of gene position and subsequently for the construction of linkage...
