Detection and frequency analysis of a slower electrophoretical allele at GPDH locus in a natural population of Drosophila melanogaster from Turkey

A new allele of aGpdh locus was detected in a population Drosophila melanogaster from Ankara province of Turkey. This allele (designated S') is slower in mobility than the common Slow (S) allele at aGpdh locus and appears in low frequency. A comparison with another locus, Adh (alcohol dehydrogenase), from the same individual flies indicates that this lower frequency could be explained less by sampling error (drift).
