Gene variants may help to distribute the work of evolution between men and women

Scientists from deCODE genetics today report the discovery of two common, single-letter variants in the sequence of the human genome (SNPs) that regulate one of the principle motors of evolution. Versions of the two SNPs, located on chromosome 4p16, have a genome-wide impact on the rate of recombination - the reshuffling of the genome that occurs in the formation of eggs and sperm.
