Abstract

During the four decades or more since Dobzhansky introduced the term 'coadaptation' to refer to the commonly observed selective superiority of inversion heterozygotes in populations of Drosophila pseudoobscura, the definition of the term has evolved, as have views concerning the rapidity with which coadaptation might occur. Indeed, the paucity of demonstrated instances of linkage disequilibrium in natural populations has led many to dismiss coadaptation as a factor in evolutionary change. The present article reviews the reasons why coadaptation (and the equivalent expression, 'integration of gene pools') was proposed as a phenomenon occurring in local (or experimental) populations, offers supporting data obtained through a reanalysis of data on irradiated populations of D. melanogaster, and concludes that sound evidence supports coadaptation as a factor in the genetic change of populations.65 references.

Detection of sympatric sibling species using genetic correlation analysis. I. Two loci, two gamodemes

Journal Article Makela, M; Richardson, R - Genetics; (United States)

Four models are presented describing zygotic frequencies at two loci for one or two sympatric but genetically differentiated populations or ''gamodemes.'' Linkage disequilibrium within gamodemes is allowed in two of the models. Maximum likelihood criteria are used to fit the models to the observed numbers of zygotes in a sample. A fitting-testing sequence for choosing a best model is described and the power of the test is analyzed. The statistical characteristics of the genetic parameter estimates were examined by simulation studies. In general, estimates were reliable when allele frequency differences between gamodemes were greater than 0.30 at both loci. Thismore »« less
Frequency-dependent selection at the PGM-1 locus of Drosophila pseudoobscura

Journal Article Snyder, T; Ayala, F - Genetics; (United States)

Frequency-dependent fitness was studied at the Pgm-1 locus of Drosophila pseudoobscura with respect to two fitness components: rate of development and larva-to-adult survival. The Pgm-1 locus is very polymorphic with only two alleles, Pgm-1/sup 100/ and Pgm-1/sup 104/, occurring at high frequencies. For each of these two alleles, 20 homozygous strains were obtained from a sample of 1140 wild-inseminated females. First-instar larvae of the two genotypes were combined in a set of eight different frequencies: 0.0, 0.10, 0.25, 0.40, 0.60, 0.75, 0.90, and 1.0. Frequency-dependent fitness effects were observed for the two survival-related fitness components examined: larvae of the lessmore »« less
A Conserved Developmental Patterning Network Produces Quantitatively Different Output in Multiple Species of Drosophila

Journal Article Fowlkes, Charless; Eckenrode, Kelly; Bragdon, Meghan; ... - PLoS Genetics

Differences in the level, timing, or location of gene expression can contribute to alternative phenotypes at the molecular and organismal level. Understanding the origins of expression differences is complicated by the fact that organismal morphology and gene regulatory networks could potentially vary even between closely related species. To assess the scope of such changes, we used high-resolution imaging methods to measure mRNA expression in blastoderm embryos of Drosophila yakuba and Drosophila pseudoobscura and assembled these data into cellular resolution atlases, where expression levels for 13 genes in the segmentation network are averaged into species-specific, cellular resolution morphological frameworks. We demonstratemore »« less

Genetic diversity and linkage disequilibrium in Drosophila melanogaster with different rates of development

Journal Article Marinkovic, D; Tucic, N; Moya, A; ... - Genetics; (United States)

The authors examined eight enzyme polymorphisms in groups of Drosophila melanogaster flies with fast, intermediate and slow development. The allelic frequencies are similar in all three developmental classes, but the distribution of the genotypes among the class is significantly heterogeneous for the three loci on the second chromosome. When the total sample of 300 individuals is examined, significant gametic disequilibrium appears in 3 out of 13 pairs of genes located on the same chromosome and in 4 out of 15 pairs of genes located on different chromosomes. This 25% incidence of disequilibrium between pairs of genes is larger than previouslymore »« less
Constraints on intron evolution in the gene encoding the myosin alkali light chain in Drosophila

Journal Article Leicht, B; Muse, S; Hanczyc, M - Genetics

Interspecific comparisons of intron sequences reveal conserved blocks of invariant nucleotides and several other departures from the strictly neutral model of molecular evolution. To distinguish the past action of evolutionary forces in introns known to have regulatory information, we examined nucleotide sequence variation at 991 sites in a random sample of 16 Drosophila melanogaster alleles of the gene encoding the myosin alkali light chain (Mlc1). The Mlc1 gene of D. melanogaster encodes two Mlc1 isoforms via developmentally regulated alternative pre-mRNA splicing. Analyses of these data reveal that introns 4 and 5, which flank the alternatively spliced exon 5, have reducedmore »« less
