● `color{Brown}"Inbreeding"` refers to the mating of more `color{Violet}"closely related individuals"` within the same breed for `color{Violet}"4- 6 generations"`.
● The breeding strategy is as follows – `color{Violet}"superior males"` and `color{Violet}"superior females"` of the same breed are identified and `color{Violet}"mated in pairs"`.
● The `color{Violet}"progeny"` obtained from such matings are `color{Violet}"evaluated"` and superior males and females among them are `color{Violet}"identified for"` `color{Violet}"further mating"`.
● A `color{Brown}"superior female"`, in the case of cattle, is the cow or buffalo that produces `color{Violet}"more milk per lactation"`.
● On the other hand, a `color{Brown}"superior male"` is the bull, which gives rise to `color{Violet}"superior progeny"` as compared to those of other males.
● A similar strategy as used by `color{Violet}"Mendel"` in developing `color{Violet}"homozygous purelines"` is used for developing purelines in cattle as was used in case of peas.
● Inbreeding increases `color{Violet}"homozygosity"`.
● Thus inbreeding is necessary if we want to `color{Violet}"evolve a pureline"` in any animal.
● Inbreeding exposes `color{Violet}"harmful recessive gene"`s that are `color{Violet}"eliminated by selection"`.
● It also helps in accumulation of `color{Violet}"superior genes"` and elimination of `color{Violet}"less desirable genes"`.
● Therefore, this approach, where there is `color{Violet}"selection at each step"`, increases the productivity of `color{Violet}"inbred population"`.
● However, `color{Violet}"continued inbreeding"`, especially close inbreeding, usually `color{Violet}"reduces fertility"` and even `color{Violet}"productivity"`.
● This is called `color{Brown}"inbreeding depression"`.
● Whenever this becomes a problem, `color{Violet}"selected animals"` of the breeding population should be mated with `color{Violet}"unrelated superior animals"` of the same breed.
● This usually helps `color{Violet}"restore fertility"` and `color{Violet}"yield"`.
