Genetic variability of two sub-populations of native guinea pig (Cavia porcellus) from southern Ecuador.

摘要: The current growing need to conserve local animal genetic resources as sources of genetic variability (GV), raises the need to carry out research that helps to know their current state; for this reason, the GV of two native subpopulations of guinea pigs (Cavia porcellus) called: Azuay and Cañar, geographically located in the south of Ecuador, was studied. For its characterization, six-microsatellite DNA markers were used, sampling 50 animals from each subpopulation and a third group of 50 animals of Peruvian origin as an external group for comparison. Of the six markers used, five could be amplified; a considerable number of alleles (9.8) was found in the general population and a value of (7.02) the same in both populations with a high degree of polymorphism (PIC=0.7035); two loci studied, MS I in both subpopulations and MS III in Azuay, were not found in HW equilibrium. GV was high in both subpopulations …
