This review paper summarizes available knowledge on the genetic manipulation of litter size in pigs. Selection among breeds permits the exploitation of existing variation and this has already proceeded much further in Europe than in the United States. Crossbreeding strategies are available to enable the commercial herd to maximize sow productivity while ensuring carcasses acceptable to each par...

Vaccinium meridionale (section Pyxothamnus ), a tetraploid species native to higher altitude locations in Jamaica, Colombia, and Venezuela, is of considerable interest blueberry breeders for its profuse, concentrated flowering monopodial plant structure, both which may be useful breeding mechanical harvest. In this study, V. was successfully hybridized as male with 4 x corymbosum Cyanococcus , ...

Abstract Accretion discs around super-massive black holes (SMBH) not only power active galactic nuclei (AGNs), but also host single and binary embedded stellar-mass (EBHs) that grow rapidly from gas accretion. The merger of these EBHs provides a promising mechanism for the excitation some gravitational wave events observed by LIGO-Virgo, especially those with source masses considerably larger t...
