Genetic recombination and molecular evolution
Gordo, I.; Charlesworth, B.; Kaiser, V.B.; Betancourt, A.J.Reduced rates of genetic recombination are often associated with reduced genetic variability and levels of adaptation. Several different evolutionary processes, collectively known as Hill–Robertson (HR) effects, have been proposed as causes of these correlates of recombination. Here, we use DNA sequence polymorphism and divergence data from the noncrossing over dot chromosome of Drosophila to discriminate betwe...
Muller’s ratchet and the pattern of variation at a neutral locus
Gordo, I.; Navarro, A.; Charlesworth, B.The levels and patterns of variation at a neutral locus are analyzed in a haploid asexual population Undergoing accumulation of deleterious mutations due to Muller's ratchet. We find that the movement Of Muller's ratchet can be associated with a considerable reduction in genetic diversity below classical neutral expectation. The extent to which variability is reduced is a function Of the deleterious initiation ...
