TLDR
The most extensive treatment of any living genus thus far attempted, this book deals with the evolution of Drosophila as demonstrated by living forms, and is mainly concerned with isolating mechanisms, genetic systems shown by hybrids and the cytology of over one third of the known species of the genus.Abstract:

Journal ArticleDOI
Inbreeding depression and its evolutionary consequences
TL;DR: The evidence that the evolution of breeding systems of animals and plants has been significantly influenced by the occurrence of inbreeding depression is reviewed, and the contemporary genetic theory of inmarriage depression and heterosis and the experimental data concerning the strength of in breeding depression are considered.
Journal ArticleDOI
The role of hybridization in evolution
TL;DR: Fisher’s model of stabilizing selection on multiple traits, under which reproductive isolation evolves as a side‐effect of adaptation in allopatry, confirms a priori arguments that while recombinant hybrids are less fit on average, some gene combinations may be fitter than the parents, even in the parental environment.
Journal ArticleDOI
The Relative Rates of Evolution of Sex Chromosomes and Autosomes
TL;DR: The frequently disproportionate effects of the sex chromosomes on interspecific inviability or sterility are consistent with the hypothesis that the gene differences concerned involve recessive or partially recessive alleles fixed by selection.
Journal ArticleDOI
Effective deme sizes during long-term evolution estimated from rates of chromosomal rearrangement.
TL;DR: This article developed population genetic models to determine how the fixation rates of negatively heterotic chromosomal rearrangements are influenced by the spontaneous occurrence rates, strengths of selection against heterozygotes, the effective size of demes (or local populations), interdeme migration rates, local extinction and colonization, and other factors.

Suture-Zones of Hybrid Interaction Between Recently Joined Biotas
TL;DR: From a study of the geographic occurrences of contemporary hybridization among North American animals, it has become apparent that most of the hybrids are produced in a few relatively localized zones, with little hybridizing in the vast areas between these zones of mixing.
