FITNESS OF KARYOTYPES IN DROSOPHILA PSEUDOOBSCURA [PDF]
Genetics, 1975 ABSTRACT In the dynamics of the survival of chromosomal polymorphism selection may be operating at the genic level, at the chromosomal level or at the supergene level. Tests designed to distinguish between these levels were run on Drosophila pseudoobscura.

Parametric alignment of Drosophila genomes. [PDF]
PLoS Computational Biology, 2006 The classic algorithms of Needleman-Wunsch and Smith-Waterman find a maximum a posteriori probability alignment for a pair hidden Markov model (PHMM). To process large genomes that have undergone complex genome rearrangements, almost all existing whole ...

Ancestral polymorphisms explain the role of chromosomal inversions in speciation. [PDF]
PLoS Genetics, 2018 Understanding the role of chromosomal inversions in speciation is a fundamental problem in evolutionary genetics. Here, we perform a comprehensive reconstruction of the evolutionary histories of the chromosomal inversions in Drosophila persimilis and D ...

SELECTION BY FERTILITY IN DROSOPHILA PSEUDOOBSCURA [PDF]
Genetics, 1974 ABSTRACT Fertility, the component of selection due to female fecundity and male mating success, differed significantly among the ST/ST, ST/AR, and AR/AR karyotypes in experimental populations and varied with karyotypic frequency. In relation to ST/AR, ST/ST females and males had higher fertilities at low frequency; AR/AR males and ...

How chromosomal inversions reorient the evolutionary process
Journal of Evolutionary Biology, Volume 36, Issue 12, Page 1761-1782, December 2023., 2023 Inversions often play key roles in adaptation and speciation, but the processes that direct their evolution are obscured by the characteristic that makes them so unique (reduced recombination between arrangements). In this review, we examine how different mechanisms can impact inversion evolution, weaving together both theoretical and empirical studies.

PLoS Genetics, 2009 In nature, closely related species may hybridize while still retaining their distinctive identities. Chromosomal regions that experience reduced recombination in hybrids, such as within inversions, have been hypothesized to contribute to the maintenance ...

Mistaken Identity: Another Bias in the Use of Relative Genetic Divergence Measures for Detecting Interspecies Introgression. [PDF]
PLoS ONE, 2016 Measures of genetic divergence have long been used to identify evolutionary processes operating within and between species. However, recent reviews have described a bias in the use of relative divergence measures towards incorrectly identifying genomic ...

Ethology, Volume 129, Issue 10, Page 515-526, October 2023., 2023 Our study in Tenebrio molitor employed behavioral and proteomic analyses to establish a correlation between female mate choice and molecular changes in the female brain. We found that females preferred mating with more attractive males, who in turn had a greater likelihood of successfully mating and producing more larvae with attractive males than with

Sex-specific embryonic gene expression in species with newly evolved sex chromosomes. [PDF]
PLoS Genetics, 2014 Sex chromosome dosage differences between females and males are a significant form of natural genetic variation in many species. Like many species with chromosomal sex determination, Drosophila females have two X chromosomes, while males have one X and ...

MODIFIERS AND “SEX RATIO” IN DROSOPHILA PSEUDOOBSCURA [PDF]
Evolution, 1978 The "sex ratio" (SR) inversions found on the X chromosomes of several Drosophila species cause males to produce progeny consisting almost entirely of females; of those few sons produced some are XY and some are XO (Sturtevant and Dobzhansky, 1936). The XO sons are sterile.
