This low genetic diversity might be attributable to population bottlenecks due to historical environmental variations and/or the recent foundation of populations in the marginal areas of its inhabitable range.
Invasive species provide opportunities for investigating evolutionary aspects of colonization processes, including initial foundations of populations and geographic expansion.
In addition to these practical considerations, biological invasions provide opportunities to investigate various aspects of the colonization process, including initial foundations of populations and patterns of geographic expansion into new areas.
Furthermore, they do not help clarify the early events of the foundation of this population.
In this paper, we have modeled a simple pleiotropic QTL with alleles affecting two traits with the same direction and having an ideal allelic correlation (=1) in a gamete at the foundation of the population.
Thus, even if there is a perfect correlation (= |1|) between two alleles at linked loci on a gamete at the foundation of a population, it will be reduced by random mating in future generations unless linkage is complete (i.e. c = 0.0).
Thus, our results prompt questions on the processes occurring during the foundation of new populations that could affect gene flow between populations, and consequently their genetic differentiation.
Thus, during the foundation of new populations inbreeding depression may provide opportunities for new immigrants, increasing gene flow between populations, and affecting genetic differentiation.
In 1964 Hamilton accepted a teaching position at Imperial College, London, and published "The Genetical Evolution of Social Behaviour," a paper that laid the foundation for population genetics studies of social behaviour.
