Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.

Bay scallops (Argopecten irradians) are a commercially important bivalve species for fisheries and aquaculture in China, the USA, Peru and Chile, but their small size and serious inbreeding depression restrict the sustainable development of their ...

Prospects of utilization of inter-subspecific heterosis between indica and japonica rice
The Asian cultivated rice (Oryza sativa L.) grown worldwide is divided into two subspecies, indica and japonica. It is well known that the heterosis of inter-subspecies is usually stronger than that of intra-subspecies.

A novel approach identifying hybrid sterility QTL on the autosomes of Drosophila simulans and D. mauritiana. [PDF]
When species interbreed, the hybrid offspring that are produced are often sterile. If only one hybrid sex is sterile, it is almost always the heterogametic (XY or ZW) sex.

Potential Association of Reactive Oxygen Species With Male Sterility in Peach
Male sterility is an important agronomic trait for hybrid vigor utilization and hybrid seed production, but its underlying mechanisms remain to be uncovered.

High-resolution genome-wide dissection of the two rules of speciation in Drosophila. [PDF]
Postzygotic reproductive isolation is characterized by two striking empirical patterns. The first is Haldane's rule--the preferential inviability or sterility of species hybrids of the heterogametic (XY) sex.

Epistasis and hybrid sterility inSaccharomyces [PDF]
Hybrid sterility is thought to be due to deleterious epistatic interactions between genes from different species. Here we demonstrate that dominant genic incompatibility does not contribute to sterility in hybrids between Saccharomyces cerevisiae and five closely related species.

SEX-LINKED HYBRID STERILITY IN A BUTTERFLY [PDF]
Recent studies, primarily in Drosophila, have greatly advanced our understanding of Haldane's rule, the tendency for hybrid sterility or inviability to affect primarily the heterogametic sex (Haldane 1922). Although dominance theory (Turelli and Orr 1995) has been proposed as a general explanation of Haldane's rule, this remains to be tested in female ...

Gene, protein and network of male sterility in rice
Rice is one of the most important model crop plants whose heterosis has been well exploited in commercial hybrid seed production via a variety of types of male sterile lines. Hybrid rice cultivation area is steadily expanding around the world, especially

Male sterility and hybrid breeding in soybean
Abstract Hybrid breeding can help us to meet the challenge of the growing world population with limited agricultural land. The demand for soybeans is expected to grow, however the hybrid soybean is still in the process of commercialization even though considerable progress has been made in soybean genome and genetic studies in recent years ...
