Abstract

The temporal dynamics of genomic variation in the Uman’ (Ukraine) population of Drosophila melanogaster over the period 1984–2004 was studied using multilocus ISSR markers. Considerable polymorphism of the genomic DNA fragments corresponding to ISSR markers was found in the D. melanogaster population studied: the values of average heterozygosity varied from 0.085 to 0.127 depending on the year. Significant differences in the frequencies of dominant alleles between the samples of different years were recorded for 12 of the 30 DNA fractions detected. These changes are nondirectional and random. The pattern of detected variation suggests the determining influence of gene drift and migration process on the variation of noncoding DNA sequences in the Uman’ population of D. melanogaster.
