The founder effect on genetic variability of experimental populations of mosquito fish were measured by the allozymes
electrophoretic technique by Leberg (1992), who estimated the values of proportion of polymorphic loci, number of alleles per locus and heterozygosity.
Alleles were labeled alphabetically, in order of decreasing electrophoretic mobility of their corresponding allozymes
ABSTRACT Genetic variation was investigated using allozymes
, cytochrome c oxidase subunit I, internal transcribed spacer region 1, and microsatellite markers in mainland and insular populations of the carpet shell Riuiitapes decussatus from the western and eastern Mediterranean Basin.
, the genetic distance indexes resulted in a low to moderate differentiation between PMA and SSF (Nei's D = 0.
These authors based this idea from the zero genetic diversity found in the populations studied with allozymes
Staining pattern and genetic interpretation of band patterns of allozymes
followed standard principles of Wendel and Weeden (1989).

, external morphology, osteology, mitochondrial DNA, and nuclear DNA (Wainwright and Lauder, 1992; Mabee, 1993; Near et al.
have been used for a number of years to describe chum salmon population differentiation and structure (Okazaki, 1982a; Kijima and Fujio, 1982; Wilmot et al.
Although the validity of allozymes
for phylogenetic inferences is questionable since the historical and genealogical relationship between the different alleles remains unknown (Lowe et al.
As far as the analysis of the allozymes
is concerned, seven (GLUDH*, LDH-1*, LDH-2*, LDH-3*, MDH-1*, PROT-1*, PROT-2*) out of the 20 presumptive loci investigated were monomorphic in both species.
have been detected for many mosquitoes and in some cases the isozyme characters appear to be correlated with vector status or another biological attribute.
While some have criticized the reliability of RAPDs, when used carefully, appropriately (see Methods) and in conjunction with allozymes
, both techniques are cost-effective tools to measure basic genetic variation that is more accessible to a wider audience.
