Heterosis, also known as hybrid vigor, is the superior performance of a heterozygous hybrid relative to its homozygous parents. Despite the scientific curiosity of this phenotypic phenomenon and its ...

When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents. This phenomenon is called heterosis. It can ...

Few studies quantify evolutionary processes in populations of domesticated plants in traditional farming systems. In February's Ecology Letters, Pujol, David and McKey show that these systems ...

A new study of sorghum explores the genetics of heterosis, the process by which hybrid plants perform better than the parent varieties used to create them. The new study fills in some of the gaps that ...

Abstract: Early‐generation hybrid fitness is difficult to interpret because heterosis can obscure the effects of hybrid breakdown. We used controlled reciprocal crosses and common garden experiments ...

Go to a family reunion and the keen observer can spot trait similarities in the way people look. Eye color, hair texture, and face shape are just some of the features that tend to be passed through ...

Heterosis can be separated into two basic types: direct and maternal. Direct or individual heterosis is the effect of hybrid vigor in the crossbred offspring. Performance traits normally improved in ...

For decades, embryo technologies were viewed as tools reserved for seedstock breeders, show-focused programs or those chasing the absolute top end of pedigree-driven genetics. But today, the economics ...
