Comparison of purified acid phosphatase allozymes inDrosophila virilis: Differences in carbohydrate content and composition of the allozymes

Biochemical Genetics, 1987
Three acid phosphatase (EC 3.1.3.2) allozymes (ACPH1, ACPH2, and ACPH4) of Drosophila virilis show different activities as measured by electrophoretic techniques. Recently, it was suggested that these differences are attributable to the variable ability of the allozymes to be incorporated into lysosomes (Narise, S., Genet. Res.

Allozyme polymorphism in Drosophila

Proceedings of the Zoological Society, 2014
Every population possesses genetic variations which are achieved through gene mutation, genetic recombination, hybridization, gene duplication etc. These genetic variations provide raw materials for evolutionary forces to create a better surviving species.

Thermal selection of allozyme polymorphisms in barnacles

Nature, 1977
Is protein polymorphism adaptive or neutral1? Attempts to assess the neutrality theory on the basis of gene frequencies and theoretical population genetics models seem, at least to some authors, to be unsuccessful2. Possible promising approaches involve the search for direct correlation of isozymes with the environment1 and with physiological function3.

Allozyme variation and the taxonomy of Wolffiella

Aquatic Botany, 1997
Abstract Allozyme electrophoresis was carried out to estimate genetic diversity within and assess divergence between the 10 recognized species in three sections of the aquatic angiosperm genus Wolffiella . Eleven presumptive loci were used in the calculations. Highest variation was found in W. lingulata and W.

SELECTION FOR AMYLASE ALLOZYMES INDROSOPHILA MELANOGASTER

Evolution, 1977
The biological significance of allozyme variation within natural populations has been a major source of controversy in population genetics since the first quantitative estimates of such variation were made (Lewontin and Hubby, 1966). A variety of theoretical and experimental strategies have been used in an effort to discriminate between 'neutralist ...

Allozyme Diversity in Asian Apis

2019
This chapter reviews the published studies on allozymes of Asian honey bees. Gel electrophoresis of enzymes, the protein products of genes, provided biologists with the first technique that allowed them to examine genetic diversity directly. It was soon recognized that this unanticipated wealth of genetic variability at both the population and species ...

Allozyme divergence and evolution in the genusLens

Plant Systematics and Evolution, 1985
The genusLens includes 5 taxonomic species:L. culinaris is cultivated andL. orientalis, L. odemensis, L. ervoides, andL. nigricans are wild. All the species are annual and almost exlusively selfers. The wild lentils are distributed over a large geographical area and form small disjunct populations which are composed of a small number of plants.

Allozyme Variation in Chenopodium fremontii

Systematic Botany, 1977
Allozyme variation of leucine aminopeptidase, glutamate-oxaloacetate transaminase and phosphoglucosisomerase was examined in Chenopodium fremontii, a species widely distributed in the western United States. Plants in the northern part of the range (western Nebraska, Wyoming, northern and western Colorado, and Utah) differfrom those in New Mexico ...

Inheritance of Allozymes in Coho Salmon

Transactions of the American Fisheries Society, 1998
Abstract We examined allozyme variation in the parents and offspring of 41 crossings of coho salmon Oncorhynchus kisutch. Mendelian inheritance previously unreported for Pacific salmon was confirmed at 11 loci: sAAT-4*, sAH*, ALAT*, EST-1*, βGALA*, GAPDH-2*, GPI-B2*, sMDH-A1,2*, PEPA*, PEPC*, and PNP-1*.
