Purebreds and inbreeds often carry genetic disease. ... Heterosis is a theory, where the phenomenon of crossing two inbred lines can produce descendants with superior genetic foundation. In addition to the absence of inbreeding depressing, present in inbreed and purebred dogs in general, there is some remote inbreeding in...

Its converse is heterosis, the 'hybrid vigour' manifested in increased size, growth rate or other parameters resulting from the increase in heterozygosity in F1 generation crosses between inbred lines. ... Vigour has sometimes been used as a measure (or even a near-synonym) of fitness in discussions of heterosis.

This study, therefore, was conducted to generate information on heterosis and combining ability in B. carinata. Nine inbred parents and their 36 F1s, obtained by half-diallel cross, were evaluated for 12 traits at three locations in Ethiopia.

The hypothesis that heterosis in biomass production of sorghum (Sorghum bicolor L. Moench) may be ascribed to stability in carbon exchange rate (CER) over a wide range of environmental conditions was evaluated.

Heterosis–the improvement of progeny over parents for yield or other traits–results when particular genotypes are crossed. Heterosis has been documented in alfalfa on numerous occasions, and recently, I proposed a breeding scheme to capture partial heterotic gains through the production of semihybrid cultivars.
