Genetic Slippage in Response to Sex

  title={Genetic Slippage in Response to Sex},
  author={Michael Lynch and Hong-Wen Deng},
-It is widely held that sexual reproduction enhances the potential for evolution by expanding the range of variation on which selection can act. However, when nonadditive gene action contributes to the expression of traits under selection, sexual reproduction can also result in slippage of the mean genotypic value in the direction contrary to selection. We show how the magnitude of genetic slippage depends on the extent to which segregation and recombination create maladapted genotypes. We also… CONTINUE READING
