1No evidence for a genetic association between female mating preference and male secondary sexual trait in a Lake Victoria cichlid fish显示文摘Sexual selection by female mating preference for male nuptial coloration has been suggested as a driving force in therapid speciation of Lake Victoria cichlid fish. This process could have been facilitated or accelerated by genetic associations betweenfemale preference loci and male coloration loci. Preferences, as well as coloration, are heritable traits and are probably determinedby more than one gene. However, little is known about potential genetic associations between these traits. In turbid water,we found a population that is variable in male nuptial coloration from blue to yellow to red. Males at the extreme ends of thephenotype distribution resemble a reproductively isolated species pair in clear water that has diverged into one species withblue-grey males and one species with bright red males. Females of the turbid water population vary in mating preference coincidingwith the male phenotype distribution. For the current study, these females were mated to blue males. We measured the colorationof the sires and male offspring. Parents-offspring regression showed that the sires did not affect male offspring coloration,which confirms earlier findings that the blue species breeds true. In contrast, male offspring coloration was determined by theidentity of the dams, which suggests that there is heritable variation in male color genes between females. However, we found thatmating preferences of the dams were not correlated with male offspring coloration. Thus, there is no evidence for strong geneticlinkage between mating preference and the preferred trait in thisInke van der SLUIJS Ole SEEHAUSEN Tom J.M.Van DOOREN Jacques J.M.van ALPHEN 2010Current Zoology2010,56,1:3
