SPERM PREDOMINANCE AMONG DROSOPHILA PSEUDOOBSCURA KARYOTYPES [PDF]
Female Drosophila store sperm after mating and utilize them to fertilize eggs as they are laid. Often a female mates with a second male while sperm from the first mate still remain in her sperm storage organs. Parker (1970) defined sperm competition as the interaction between, and differential utilization of, sperm from separate ejaculates.

Parametric alignment of Drosophila genomes. [PDF]
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 ...

How chromosomal rearrangements shape adaptation and speciation: Case studies in Drosophila pseudoobscura and its sibling species Drosophila persimilis. [PDF]
The gene arrangements of Drosophila have played a prominent role in the history of evolutionary biology from the original quantification of genetic diversity to current studies of the mechanisms for the origin and establishment of new inversion mutations

Genomics of Natural Populations: How Differentially Expressed Genes Shape the Evolution of Chromosomal Inversions in Drosophila pseudoobscura. [PDF]
Chromosomal rearrangements can shape the structure of genetic variation in the genome directly through alteration of genes at breakpoints or indirectly by holding combinations of genetic variants together due to reduced recombination.

A history of studies of reproductive isolation between Drosophila pseudoobscura and D. persimilis [PDF]
Drosophila pseudoobscura and D. persimilis are a sister species pair that have been used as a model for studies of reproductive isolation and speciation for almost 100 years owing to their close evolutionary history, well characterized genetic ...

Evidence for stabilizing selection on codon usage in chromosomal rearrangements of Drosophila pseudoobscura. [PDF]
There has been a renewed interest in investigating the role of stabilizing selection acting on genome-wide traits such as codon usage bias. Codon bias, when synonymous codons are used at unequal frequencies, occurs in a wide variety of taxa.

Inversions in the third chromosome of wild races of Drosophila pseudoobscura, and their use in the study of the history of the species [PDF]
Genetic studies showed several years ago that the third chromosomes of wild strains of Drosophila pseudoobscura often carry suppressors of crossing-over.

How hot are drosophila hotspots? examining recombination rate variation and associations with nucleotide diversity, divergence, and maternal age in Drosophila pseudoobscura. [PDF]
Fine scale meiotic recombination maps have uncovered a large amount of variation in crossover rate across the genomes of many species, and such variation in mammalian and yeast genomes is concentrated to

Divergence of X-linked trans regulatory proteins and the misexpression of gene targets in sterile Drosophila pseudoobscura hybrids [PDF]
Background The genetic basis of hybrid incompatibilities is characterized by pervasive cases of gene interactions. Sex chromosomes play a major role in speciation and X-linked hybrid male sterility (HMS) genes have been identified. Interestingly, some of
