Inbreeding: It refers to the mating of more closely related individuals within the same breed for 4-6 generations.
-
Outbreeding: It is the breeding of unrelated animals, which may be between individuals of the same breed (but having no common ancestors), or between different breeds (cross- breeding) or different species (inter-specific hybridisation).
-
Inbreeding depression is the loss in vigour associated with inbreeding.
-
Cross-breeding is the crossing of two breeds of the same species.
-
Differences between Intraspecific Hybridisation and Interspecific Hybridisation
-
Artificial insemination involves the collection of semen from a high-quality bull and its introduction into the body of the female by artificial means.

Multiple ovulation embryo transfer technology (MOET)
-
Apiculture is the maintenance of hives of honeybees for the production of honey.
-
Fishery is an industry devoted to the catching, processing or selling of fish, shellfish or other aquatic animals.
-
Plant breeding is the purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation, give better yields and are resistant to diseases.
-
Steps Involved in Plant Breeding
-
Selection is the differential reproduction of individuals in a population.
-
Biofortification means to breed crops with higher levels of vitamins and minerals or higher proteins and healthier fats.
-
Single cell protein (SCP) is a microbial biomass rich in high-quality protein.
-
Plant tissue culture is the maintenance and growth of plant cells.
-
Explant is the plant part excised from its original location and used for initiating culture.
-
The capacity to generate a whole plant from any cell/explant is called totipotency.
-
The method of producing thousands of plants through tissue culture is called micropropagation.
-
A hybrid produced by the fusion of somatic cells of two different varieties or species is called a somatic hybridisation.
