Genetics of recombination rate variation within and between species.

ABSTRACT: Recombination diversifies the genomes of offspring, influences the evolutionary dynamics of populations, and ensures that chromosomes segregate properly during meiosis. Individuals recombine at different rates, but observed levels of variation in recombination rate remain mostly unexplained. Genetic dissection of differences in recombination rate within and between species provides a powerful framework for understanding how this trait evolves. In this Perspective, I amalgamate published findings from genetic studies of variation in the genome-wide number of crossovers within and between species, and I use exploratory analyses to identify preliminary patterns. The narrow-sense heritability of crossover count is consistently low, indicating limited resemblance among relatives and predicting
