Recombination takes place during meiosis, when maternal and paternal genes are regrouped in the formation of gametes (sex cells).
WebGenetic drift can result in genetic traits being lost from a population or becoming widespread in a population without respect to the survival or reproductive value of the alleles involved. A random statistical effect, genetic drift can occur only in small, isolated populations in which the gene pool is small enough that chance events can ...
