Consequently, inbreeding depression due to lethal mutations remains unchanged for all levels of geneflow, and results are almost identical to those for single populations. With a continuum of alleles, geneflow inflates the genetic variance in the same way as a source of mutations of small effect. In large populations, selection acting on genetic markers may bias estimates of geneflow. For example, geneflow between populations with different mating systems could affect the rate at which purging might occur. Analysis of koala populations at intermediate geographic distances would be required to assess geneflow accurately. Thus, in a two-dimensional population, barriers to geneflow can be detected through their effect on the spatial pattern of genetic marker alleles. The effects of such barriers to geneflow are of interest from several points of view. It would be interesting to investigate the effects of barriers to geneflow on genealogical structure in more detail. Within group genetic differentiation and geneflow are shown on the diagonal in bold. Samples from additional populations are required to confirm the picture of geneflow presented here. In anticipation of area-wide control programmes, estimates of geneflow among tsetse populations are necessary. The effects of such an expansion are to diminish estimates of genetic differentiation which leads to an overestimate of geneflow. Thus, our estimates of geneflow are exaggerated, perhaps grossly so. Influence of geneflow and breeding tactics on gene diversity with populations. One explanation is that they simply represent geneflow that occurs between the cryptic species. Correlation of pairwise genetic and geographic distance measures : inferring the relative influences of geneflow and drift on the distribution of genetic variability. Because of crawlaway juveniles, geneflow is limited and local snail populations could possibly become differentially adapted to trematodes. Thus, even if a homozygous hybrid genotype is fitter, it may be very unlikely to be established in the face of geneflow and recombination. However, escalating divergence of the populations is unlikely in the presence of geneflow unless they experience persistently different selection pressures. For populations from different continents to share even 'one migrant per generation', geneflow among populations should in theory be high. The occurrence of significant geneflow between populations provides interesting additional supporting evidence for their dispersal potential. There has thus probably always been a continuous channel for geneflow between human populations and more intermixture than in other animal groups. This term is used to describe subpopulations which are distinguished by behavioural differences, but between which there is still a considerable amount of geneflow. As such, the host-parasite interaction significantly affects the development of infestations and therefore the potential for transfer of the parasite or geneflow between populations. Such a pattern is suggestive of low geneflow among local populations. Habitats include the coastal, semi-desert, savannas and forests, some of which may act as physical barriers to geneflow.
