- Superior males and females of the same breed are identified and mated.

- In case of cattle, more milk per lactation is the criteria for superior female for cow and buffalo. Whereas a superior male is the one who give rise to superior progeny.
- Inbreeding may be explained by taking an example of cows and bulls.
- Superior cows and superior bulls of the same breed are identified and mated.
- The progeny obtained from such mating are evaluated and superior males and females are identified for further mating.
- A superior female, in the case of cattle, is the cow that produces more milk per lactation.
- A superior male is that bull, which gives rise to superior progeny as compared to those of other males.
