The low geneticdivergence of the three invasive molluscs is associated with hermaphroditic reproduction, mainly by selfing. Neither the groups nor the clusters exhibited appreciable levels of geneticdivergence. The geneticdivergence presented in this paper seems to be much deeper in comparison to other animal groups. The most striking result was the association between region of origin, host type and geneticdivergence. That is, in the context of the model presented here, clashes are due to differing selection pressures and not cryptic geneticdivergence. The fact, therefore, that important variation was found in such a conservative gene suggests that a substantial degree of geneticdivergence exists within the species. This may also account for the greater level of geneticdivergence found for equine strongylids. Electrophoretic differences among these species show no correlation between geneticdivergence and strong reproductive isolation. Host-addition as defined earlier, followed by geneticdivergence towards speciation in allopatry, appear to offer a better explanation. Second, reduced geneticdivergence will limit the ability of the population to evolve. Geneticdivergence among flukes was analysed within and between hosts and among geographic areas using enzyme polymorphism. Geneticdivergence (spatial and temporal) at the level of chromosomal polymorphism among natural populations was calculated. Small isolated fragments are expected to have smaller population size, low genetic variation, increased interpopulation geneticdivergence due to increased random drift, elevated inbreeding and reduced gene flow. The genetic variance will increase further if there is also cryptic geneticdivergence between the two demes, resulting in more than the minimum number of clashes. A parthenogenetic mode of reproduction may be responsible for the low levels of variation found, as well as for the relative lack of geneticdivergence between populations. Researchers who have tried to analyse characteristic developmental patterns, the speed of dispersal or the degree of geneticdivergence in populations of alien species have come to different conclusions. Although these experiments are limited to laboratory conditions, they show that selection may promote geneticdivergence even in populations living in identical environments, if they find alternative adaptive solutions. The second main finding is that there is a general deficiency of heterozygote individuals and high levels of geneticdivergence between samples from the same population. This low level of dispersal has led to geneticdivergence across its range. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
