- Abstract
Given the hybridization ability between species Mytilus edulis platensis and M. galloprovincialis, this research proposed to assess the genetic variability of the hybrid offspring in relation to pure species, using 8 loci microsatellites. The study found differences between hybrid offspring comparing to pure species. The hybrid offspring had the highest observed mean heterozygosity values (Ho = 0,63 ± 0,28) and low values of inbreeding, which tend to significant deviations to negative values of (Fis), demonstrating excess of heterozygote in hybrids comparing with pure species, which displayed significant deviations towards positive values of Fis. The principal component analysis shows three distinct groups among the samples analyzed, identifying the hybrid offspring as an intermediate group between pure species.
