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.
In the present work, allozyme electrophoresis was used to study genetic variation among the five color morphotypes of P.
Genotypic and allelic frequencies were determined by direct counts from allozyme phenotypes, and the resulting data were analyzed by various statistical methods to describe the genetic structure of the Ruditapes decussatus populations.

These authors based this idea from the zero genetic diversity found in the populations studied with allozymes markers.

Okazaki (1982b), in a study evaluating allozyme variation in Asian and North American populations, concluded that there were 11 geographically based regional groups of populations across the Pacific Rim.
However, Hamrick and Godt's (1989) review of the allozyme literature revealed that, while some geographically widespread species typically have a greater proportion of genetic variation partitioned within populations, there is no significant difference between geographically widespread and restricted species in how genetic variation is partitioned.
It is possible that there was a defect in the allozyme markers used in the previous investigation or that there were newly founded colonies under genetic drift at the time of the previous research.
