Thus, ranchers have changed their cattle-breeding programs to meet this new demand. For example, consumers want leaner beef that is tender. When this happens, breeders have to adjust their program, which results in less-efficient selection than if the new breeding goal had been used from the beginning. Sometimes the marketplace demands a different product than was defined as desirable in the original breeding objective. Ultimately, breeding goals are dictated by market demand however, it is not easy to predict what consumers will want several years in advance. Complicating the implementation of a breeding program is the number of generations needed to reach the initial goals. Choice of breeding goals and design of an effective breeding program is usually not an easy task.

Inbreeding can lead to a reduced gene pool, making it more difficult to produce new varieties in the future. Genes and their different alleles within a population are known as its gene pool.
Benefits and risks of selective breedingīecause of selective breeding, future generations of selectively bred plants and animals will all share very similar genes which will reduce variation. For example, they may provide more or better quality food, or allow farmers to feed more people. The new varieties may be economically important.
