The allelic state of gene flamenco has been determined in a number of Drosophila melanogaster strains using the ovoD test. The presence of an active copy of gypsy in these strains was detected by restriction analysis. Then male reproduction behavior was studied in the strains carrying a mutation in gene flamenco. In these experiments mating success has been experimentally estimated in groups of flies. It has been demonstrated that the presence of mutant allele flam
MS decreases male mating activity irrespective of the presence or absence of mutation white.The active copy of gypsy does not affect mating activity in the absence of the mutation in gene flamenco. Individual analysis has demonstrated that mutation flam
MS results in characteristic changes in courtship: flam
MS males exhibit a delay in the transition from the orientation stage to the vibration stage (the so-called vibration delay). The role of locus flamenco in the formation of male mating behavior in Drosophila is discussed. 相似文献

The distribution of two variants of MDG4 (gypsy) was analyzed in severalDrosophila melanogasterstrains. Southern blot hybridization revealed the inactive variant of MDG4 in all strains examined and active MDG4 only in some of them. Most of the strains harboring the active MDG4 variant were recently isolated from natural populations. It is of interest that the active MDG4 prevailed over the inactive one only in strains carrying the mutantflamenco gene. Several lines were analyzed in more detail. The number of MDG4 sites on salivary-gland polytene chromosomes was established via in situ hybridization, and MDG4 was tested for transposition using the ovoD test. 相似文献
