http://inspiredraceevents.com/host-a-race/ WebA host race represents the population of a particular species which is reproductively isolated from the distinct conspecific population as an immediate effect of adaptation to a particular host. It was given by Diehl and bush in the year 1984. Overview of Host Race WebSpeciation is thereby envisaged as having two phases: (i) the evolution of host races from within polymorphic, panmictic populations; and (ii) further reduction of gene flow between host races until the diverging populations can become generally accepted as species. We apply this criterion to 21 putative host race systems. my tiny hands please wash sign
