Lack of correlation between mating activity and EST-1 polymorphism in three natural and laboratory populations of Drosophila bipectinata.

ABSTRACT

Est-1 polymorphism and mating activity have been studied in three natural populations of D. bipectinata and after 10 generations of their maintenance in the laboratory. The results indicate that the enzyme Est-1 variation was not significant within natural populations within F10 generation and also between different natural populations and F10 generation indicating the role of balancing selection in the maintenance of enzyme polymorphism in both natural and laboratory conditions. On the other hand, there was variability in the mating activity within natural populations and within F10 generation and also between natural population and F10 generation. However, there was no correlation between Est-1 polymorphism and mating activity.
