ملخص

Genetic variability and similarity were analysed in four parthenogenetic and five bisexual populations of the snail Melanoides tuberculata found in Israel. Electrophoretic studies of six enzymatic systems revealed 28 zones of activity. The average genetic identity between populations was low—0.725. A particularly low similarity (0.628) was obtained between parthenogenetic populations, compared to the average of 0.822 observed among the bisexual ones. The percentage of fixed electrophoretic bands in parthenogens was 53.9% compared to 12.5% observed in bisexual populations. The diversity of parthenogenetic populations was found to be lower than those of bisexual. The amount of electrophoretic diversity between populations of the parthenogenetic group was found to be 80%, whereas within the bisexual group the diversity between populations was only 42%.
