AVSAB is concerned with the recent re-emergence of dominance theory and forcing dogs and other animals into submission as a means of preventing and correcting behavior problems. For decades, some traditional animal training has relied on dominance theory and has assumed that animals misbehave primarily because they are striving for higher rank. This idea often leads trainers to believe that for...

The dominance of deleterious mutations has important consequences for phenomena such as inbreeding depression, the evolution of diploidy, and levels of natural genetic variation. Kacser and Burns' metabolic theory provides a paradigmatic explanation for why most large-effect mutations are recessive. According to the metabolic theory, the recessivity of large-effect mutations is a consequence of...

During the process of speciation, diverging taxa often hybridize and produce offspring wherein the heterogametic sex (i.e., XY or ZW) is unfit (Haldane's rule). Dominance theory seeks to explain Haldane's rule in terms of the difference in X-linked dominance regimes experienced by the sexes. However, X inactivation in female mammals extends the effects of hemizygosity to both sexes. Here, we hi...

Errors pertaining to the following physical theories are discussed: the Dirac magnetic monopole theory; the KleinGordon equation; the Yukawa theory of nuclear force; the idea of Vector Meson Dominance; the Aharonov-Bohm effects; the idea of diffraction-free electromagnetic beams and Quantum Chromodynamics. Implications of the theoretical errors are discussed briefly. In particular, relations be...

The "dominance theory" of HALDANE'S rule postulates that hybrids of the heterogametic sex are more likely to be inviable or sterile than the homogametic sex because some of the epistatic incompatibilities contributing to postzygotic isolation behave as X-linked partial recessives. When this is true, pairs of taxa with relatively large X chromosomes should require less divergence time, on averag...
