Species identification of two sympatric hakes by allozymic markers

open access: yesScientia Marina, 2001
Samples were collected from hake species Merluccius australis and M. hubbsi in the south west Atlantic Ocean. Enzyme electrophoretic analysis of the eye, liver and muscle revealed 5 out of 33 genetic loci with species-specific allelic frequencies.

Population genetics of the oyster Crassostrea corteziensis in the Gulf of California

open access: yesCiencias Marinas, 2008
The native oyster Crassostrea corteziensis is a cultured species along the Mexican Pacific with considerable growth potential. For this reason CIBNOR is working towards obtaining greater knowledge that can be used in the future to begin a selective ...

Genetic characterization of Apis mellifera macedonica (type “rodopica”) populations selectively controlled in Bulgaria [PDF]

open access: yesJournal of Central European Agriculture, 2016
The genetic variability in selectively controlled in Bulgaria local honey bee populations, representing Apis mellifera macedonica subspecies (type “rodopica”), has been studied by usage of alloenzymic analysis of six enzymic systems (MDH-1, ME, EST-3 ...

Genetic control of isozymes in the primary gene pool Phaseolus lunatus L. [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 1999
Suitable electrophoretic separation methods of 34 isozymes from 17 enzyme systems resolved in Phaseolus lunatus L. (Lima bean) were developed. Data from the migration of the staining zones indicated that three loci control EST, GPI, IDH and MDH ...

On gene pool divergence of the brown hare (Lepus europaeus, Pallas) in Vojvodina [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2004
Today it is widely accepted that a conservation of genetic diversity increases chances of animal survival. The aim of this study was investigation of gene pool divergence of the brown hare (Lepus europaeus) in Vojvodina.

Allozymic variation in the Pacific oyster Crassostrea gigas from San Quintín Bay,Baja California, Mexico

open access: yesCiencias Marinas, 2004
 Allozymic variability was analyzed in adult oysters Crassostrea gigas from the 1999, 2000 and 2001 crops of San Quintín Bay, Baja California, Mexico, using starch gel electrophoresis. The analysis included 13 enzymatic systems that revealed 25 loci, of

Evolutionary programmed development as the basis of Darwinian selection: A review [PDF]

open access: yesArchives of Biological Sciences, 2009
The sources of biological variation are numerous and versatile. The basic problem is to explain how this huge potential variation could be limited and reduced to adaptive combinations of allelogenes and characters.
