3: A windows program for the analysis of allozyme
and molecular population genetic data.
Thus, in this study we aimed to estimate the genetic variability of Hemiodus orthonops using the allozymes
electrophoresis technique and compare it to other species from Parana River basin, which was also studied with allozymes
Despite any such preferential crossings, allozyme
data clearly indicate that this restriction to gene flow has not been enough to determine a relevant isolation between these morphotypes.
Microsatellite DNA is effective in detecting variation in some species with low levels of either allozyme
or mtDNA polymorphism (Brunner et al.
mutations in Drosophila melanogaster: rate of occurrence and nature of the mutants.
A preliminary investigation of allozyme
genetic variation and population geographical structure in Aphanius fasciatus from Italian brackish- water habitats.

loci in four populations and at species level in T.
2006) and given its wide distribution and abundance has been subjected to a series of evolutionary investigations using several markers, including: allozymes
, external morphology, osteology, mitochondrial DNA, and nuclear DNA (Wainwright and Lauder, 1992; Mabee, 1993; Near et al.
2008b) reported that allozyme
monitoring indicated that successful introduction and establishment of broodstock from the Chitose River on the Sea of Japan coast of Hokkaido Island to the Gakko River on the Sea of Japan coast of Honshu Island accounts for observed temporal differentiation in the existing Gakko River population.
1988) compared levels of allozyme
genetic variation in both restricted and geographic widespread plant congeners including four species of Astragalus, and observed that there is considerable variance in levels of gene diversity reported for rare species.
By means of cellulose acetate gel electrophoresis, wherein 8 allozyme
loci (FUM, G6PDH, GOT, IDH, LDH, MPI, PGI, and PGM) were studied, we investigate whether the genetic variation among species is larger compared to the variation among populations within species and indicative of reproductive isolation among the species.
Thus, the cytogenetic and allozyme
data sets indicate quite different degrees of genetic divergence between M.
