Comment on "A test of the snowball theory for the rate of evolution of hybrid incompatibilities".
نویسنده
چکیده
Matute et al. (Reports, 17 September 2010, p. 1518) tested the theory that the number of genes involved in hybrid incompatibility increases faster than linearly. However, the method they used is inappropriate because it detects genes that are haploinsufficient in a hybrid background but that would not contribute to lethality in wild-type hybrids, thus overestimating the frequency of hybrid inviability.

A test of the snowball theory for the rate of evolution of hybrid incompatibilities.
Hybrids between species are often sterile or inviable because the long-diverged genomes of their parents cause developmental problems when they come together in a single individual. According to the Dobzhansky-Muller (DM) model, the number of genes involved in these "intrinsic postzygotic incompatibilities" should increase faster than linearly with the divergence time between species. This stra...
متن کاملThe Pace of Hybrid Incompatibility Evolution in House Mice.
Hybrids between species are often sterile or inviable. This form of reproductive isolation is thought to evolve via the accumulation of mutations that interact to reduce fitness when combined in hybrids. Mathematical formulations of this "Dobzhansky-Muller model" predict an accelerating buildup of hybrid incompatibilities with divergence time (the "snowball effect"). Although the Dobzhansky-Mul...
متن کاملAre species real? The shape of the species boundary with exponential failure, reinforcement, and the "missing snowball".
Under simple assumptions, the evolution of epistatic "Dobzhansky-Muller" incompatibilities between a pair of species should yield an accelerating decline of log overall reproductive compatibility--a "snowball" effect that might rapidly provide new species with "reality." Possible alternatives include: (1) simple exponential failure, giving a linear rate of log compatibility loss, and (2) "slowd...
متن کاملInheritance of Consumer Behavior: Providing a Model for Improving Banking Services Based on Meme Theory with Emphasis on Ethical Components
Background: Meme is a hereditary theory and an idea, behavior, or method that is transmitted from one person to another through culture. Inheritance theories differ in the degree of adaptation and capability, that is, adaptation to the socio-cultural environment in which they are spread. More adaptable and more capable memes will be more successful in transmitting, spreading to more people, and...
متن کاملThe Evolution of Long-term Care Programs; Comment on “Financing Long-term Care: Lessons From Japan”
The need for long-term care (LTC) represents a “new social risk,” one that overlaps with and complements systems of care that pre-date such programs, complicating LTC program design. This commentary expands on Ikegami’s discussion of how these structural factors must be accommodated, as well as historical and cultural factors that influence public expectations of such a...
