[Studies on allozyme of Gammatricula].

Zhongguo ji sheng chong xue yu ji sheng chong bing za zhi = Chinese journal of parasitology & parasitic diseases, 2003
To furnish molecular genetic evidences for taxonomy of Gammatricula.A total of 24 enzymes of 6 populations of Gammatricula songi and 1 population of Gammatricula chinensis collected from Kaihua County and Chunan County of Zhejiang Province were studied using horizontal starch gel electrophoresis.29 loci were found.

Allozyme Diversity in Cultivated Crops

Crop Science, 1997
Estimates of genetic diversity maintained by plant species and its distribution within and among populations allows plant geneticists to predict, in a general way, the evolutionary potential of species. Single‐gene markers, particularly allozymes, have been used to measure the genetic diversity of species.

Allozyme variability and relatedness in six crayfish species

Journal of Heredity, 1979
A total of twenty-six allozyme loci were assayed in six crayfish species. Estimated mean heterozygosity was low (5.5 percent) for all species in comparison with the invertebrate average. The specific values, however, ranged from 2.9 percent to 8.3 percent.

Allozymes of the Cyprinid Fishes

1984
The cyprinid fishes comprise a major element of the ichthyofauna of Africa, Asia, Europe, and North America. More than 1600 species in over 275 genera make the Cyprinidae the most speciose of fish families (Nelson, 1976). Cyprinid fishes have been the subject of several allozyme studies.

Allozyme variation in bumble bees (Hymenoptera: Apidae)

Biochemical Genetics, 1992
Allozyme variation at an average of 37.3 loci was assessed in queens of 16 Bombus and 2 Psithyrus bumble bee species from North America. The mean expected heterozygosity (H) for the Bombus species was 0.008 +/- 0.006 (95% confidence limits) and that for the Psithyrus was 0.007 +/- 0.007.

Allozyme Variation and Differentiation in African and Indian Rhinoceroses

Journal of Heredity, 1989
We studied variation at 25 to 31 allozymic loci in African and Asian rhinoceroses. Four taxa in three genera were examined: African Ceratotherium simum simum (northern white rhinoceros), C. s. cottoni (southern white rhinoceros), Diceros bicornis (black rhinoceros), and Rhinoceros unicornis (Indian rhinoceros).

Allozymic Variability in Sullivantia (Saxifragaceae)

Systematic Botany, 1982
Populations of Sullivantia species were investigated electrophoreti- cally to evaluate the effect of geographic isolation and small population size on genetic variability. Starch gel electrophoresis demonstrated that Sullivantia species are allozymically depauperate.

ISOZYMES AND ALLOZYMES: ALTERNATE FORMS OF PROTEIN ADAPTATION?

Canadian Journal of Genetics and Cytology, 1978
The hypothesis is put forward that constant or predictable environments will select for multiple locus enzymes (isozymic variation) while variable or nonpredictable environments will select for multiple alleles at single loci (allozymic variation).
