Molecular variation at the vermilion locus in geographically diverse populations of Drosophila melanogaster and D. simulans.
We surveyed nucleotide variation at vermilion in population samples of Drosophila melanogaster from Africa, Asia and the Americas to test the hypothesis that the vermilion gene was a target of balancing selection and to improve our understanding of geographic differentiation. Patterns of polymorphism and divergence showed no evidence for non-neutral evolution. However, the frequency spectrum of...
متن کاملExcess polymorphism at the Adh locus in Drosophila melanogaster.
The evolutionary history of a region of DNA encompassing the Adh locus is studied by comparing patterns of variation in Drosophila melanogaster and its sibling species, D. simulans. An unexpectedly high level of silent polymorphism in the Adh coding region relative to the 5' and 3' flanking regions in D. melanogaster is revealed by a populational survey of restriction polymorphism using a four-...
متن کاملElectrophoretic variability at the alcohol dehydrogenase locus in Drosophila melanogaster.
In crder to assess the extent of electrophoretic variation at the alcohol dehydrogenase locus in a natural population of Drosophila melanogmter KREITMAN ( 1980) screened ninety-six isochromosomal lines and two lines carrying “fast’’ thermostability variants of the enzyme using eight different conditions of acrylamide electrophoresis. Although he found no sdditional mobility variation within the...
متن کاملPosition Effects at the Hairy Locus in DROSOPHILA MELANOGASTER.
Radiation-induced chromosomal rearrangements of h(+) have given rise to several Drosophila stocks that exhibit apparent position-effect inactivation; i.e., flies carrying the rearranged chromosomes heterozygously with h show varying degrees of hairiness. The numbers of hairy chaetae produce a quantifiable index of position effect. Six such "position-allele" stocks are here discussed, both as to...
متن کاملFrequency-Dependent Selection at the LAP Locus in DROSOPHILA MELANOGASTER.
Results of fitness estimates for the Lap locus in Drosophila melanogaster revealed that under crowded media conditions gene frequency equilibrium was maintained by frequency-dependent selection. Evidence was obtained that indicated that mating and egg-to-adult viability were frequency dependent.
