Competition and Adaptation among Diploid and Polyploid Clones of Unisexual Fishesnificance of genetic variation. Here, the genetic variation of a population is contained in the form of multiple genetic clones that, in the absence of recombination, magnify the effects of selection in successive generations.

The focus on species in the modern synthesis brought a much clearer conception of the biological nature of species and some easily grasped, heuristic, models of allopatric and sympatric speciation.

Meteor Apparatebau Paul Schmeck GmbH, Siegenir phenotypic expression. For example, low- and high-fecundity phenotypes may mature at different ages or show differential survival. Correlation of traits at the level of the phenotype is the net result of genetic correlation (pleiotropism, linkage) and environmental variation that influences two or more traits simultaneously (Falconer 1960).

In contrast, species in stable communities with density dependence were expected to display traits associated with strong competitive a

The modern synthesis is characterized, perhaps above all else, both by the elaboration of mathematical structures to describe the genetic diversity and response to natural selection in populations and by a qualitative focus on the properties of
