Question

In which of the following types of breeding the superior males of one breed are mated with superior females of another breed?
A. Outcrossing
B. Cross breeding
C. Out breeding
D. In breeding

Answer 1

Hint: Breeding is the development of offspring through sexual reproduction. Only between a male and a female animal or plant it may occur. Breeding places are often chosen for very specific shelter requirements and food proximity; in addition, the breeding season is a specific time window that has evolved to suit anatomical, mating-ritual, or climatic and other ecological factors for each species.

Complete answer:
Outcrossing- The technique of crossing between various breeds with no common ancestry is out-crossing or out-breeding. This is the method of integrating genetic material that is unrelated into a breeding line. This boosts genetic diversity, thus reducing the risk of an individual being exposed to disease or genetic abnormalities. Unlike what is widely assumed, outcrossing is now the standard for the most purposeful animal breeding.
Cross breeding- The mating of animals from two breeds involves crossbreeding. Breeds that have complementary characteristics that will increase the economic benefit of the offspring are typically picked. This is the process by which the superior males of an animal of a certain breed are mated with the superior females of the same animal of another breed. This contributes to the offspring possessing the superior characteristics of both breeds.
Outbreeding- Matches between individuals from different races, subspecies, or species are referred to as outbreeding. Outbreeding may result in a decrease in reproductive fitness known as depression of outbreeding, but this is less prevalent than depression of inbreeding. Extinction risk can also be increased by outbreeding between populations with chromosomal incompatibilities or those adapted to different environmental conditions.
In breeding- The mating of similar individuals leads to inbreeding. In most species of plants and animals, it results in a drop in survival and reproduction (reproductive fitness), known as inbreeding depression. Inbreeding usually increases the risk of extinction in small populations , particularly for species that are not normally inbred.

Hence, the correct answer is (B) cross breeding

Note: The offspring is referred to as hybrid vigor, compared to the parent, which has the superior characteristics. Irresponsible crossbreeding may also create species of inferior quality or dilute a purebred gene pool to the point of extinction of a given race of organism, whereas crossbreeding is used to preserve the health and viability of species.
