Low genetic distance values were found among the studied populations. The estimate of Nem (12.3) suggests some degree of isolation between the natural and the cultured populations. The estimated mean heterozygosity values were lower than those found by other investigators for the same species elsewhere but similar to those previously reported from Greece. Consistent significant Ho heterozygote deficiency was observed at several loci. Ho and He mean values did not exhibit statistically significant changes between the two culture populations in the course of one year and three year periods. In addition the temporal genetic variation of the two cultured populations was further examined in the course of the same periods. The observed significant heterogeneity of the genotype and allele frequencies of Idh-2, Pgm-1, Est-2 loci could be caused by the possible involvement of selection.10aAllozymes10aGenetic composition10aGreece10aM. galloprovincialis10aMollusca Bivalvia10atemporal variation1 aKravva, N.1 aStaikou, A.1 aTriantaphyllidis, C.  uhttps://icgf.myspecies.info/content/genetic-composition-and-temporal-genetic-variation-mytilus-galloprovincialis-populations
