Hybrid

Hybrid refers to the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents, but can show hybrid vigour, often growing larger or taller than either parent.

Definition

The term hybrid is derived from Latin hybrida, used for crosses such as of a tame sow and a wild boar. The term came into popular use in English in the 19th century, though examples of its use have been found from the early 17th century.

Types of Hybrids

Hybrids can be classified into three types:

• Interspecific hybrids are crosses between different species within the same genus.
• Intergeneric hybrids are crosses between different genera.
• Interfamilial hybrids are crosses between different families.

Hybridization

Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization), resulting in a hybrid.

Hybrid Vigor

Hybrid vigor or heterosis is the improved or increased function of any biological quality in a hybrid offspring. It is the occurrence of a genetically superior offspring from mixing the genes of its parents.
