متن کاملB Chromosomes Have a Functional Effect on Female Sex Determination in Lake Victoria Cichlid Fishes
The endemic cichlid fishes in Lake Victoria are a model system for speciation through adaptive radiation. Although the evolution of the sex-determination system may also play a role in speciation, little is known about the sex-determination system of Lake Victoria cichlids. To understand the evolution of the sex-determination system in these fish, we performed cytogenetic analysis in 11 cichlid...
متن کاملConstruction of a BAC library for Haplochromis chilotes, a cichlid fish from Lake Victoria.
Cichlid fishes in Lake Victoria are model organisms for studying rapid radiation and speciation. On the way to examine the molecular basis of how these cichlid fishes achieved such a remarkable morphological diversification, we constructed a bacterial artificial chromosome (BAC) library derived from a cichlid species, Haplochromis chilotes, from Lake Victoria. The library includes 157,056 clone...
متن کاملPopulation-structure and genetic diversity in a haplochromine fish cichlid of a satellite lake of Lake Victoria
The ∼ 500 species of the cichlid fish species flock of Lake Victoria, East Africa, have evolved in a record-setting 100 000 years and represent one of the largest adaptive radiations. We examined the population structure of the endangered cichlid species Xystichromis phytophagus from Lake Kanyaboli, a satellite lake to Lake Victoria in the Kenyan Yala wetlands. Two sets of molecular markers wer...
متن کاملKnow thine enemy: intrasexual selection and sympatric speciation in Lake Victoria cichlid fish
It has been suggested that sympatric speciation can be driven by sexual selection on male mating traits alone. However, a fundamental problem for this process is the lack of ecological differentiation that would stabilize co-existence of incipient species through frequency-dependent selection. Such selection can also occur if male aggression is primarily directed towards similar rather than tow...
