Definition

noun, plural form: hybrids

(reproductive biology) The offspring resulting from the cross between parents of different species or sub-species

(molecular biology) A complex formed by joining two complementary strands of nucleic acids


Supplement

A hybrid, in general, refers to any of mixed origin or composition, or the combination of two or more different things. In molecular biology, a hybrid is the complex formed when two complementary strands of nucleic acids join.

In reproductive biology, a hybrid is the offspring produced from a cross between patents of different species or sub-species. Example of an animal hybrid is a mule. The animal is produced by a cross between a horse and a donkey. Liger, the offspring of a tiger and a lion, is another animal hybrid. In plants, hybridization is relatively common and several plant hybrids are produced through natural means or by assisted breeding. In agriculture, hybridization is one of the means through which crop varieties with preferred traits (e.g. improved resilience against certain diseases) are produced.

Different types of hybrids:

  • Single cross hybrid – first generation of offspring resulting from a cross between pure bred parents
  • Double cross hybrid - offspring resulting from a cross between two hybrids of single cross
  • Three-way cross hybrid – offspring from a cross between a single cross hybrid and an inbred line
  • Triple cross hybrid - offspring resulting from the crossing of two different three-way cross hybrids
  • Population hybrid – offspring resulting from the crossing of plants or animals in a population with another population. For instance, a cross between difference races


Word origin: Latin hybrida, hibrida ("a crossbred animal")
