Though crossbreeding increase Vigour in animals and crop production in plants yet there are some disadvantages: -
1.Crossbred animals have the weaknesses of the Breeds from which they decend .
2.If inferior Sire is used to bred our native females, this will result in inferior offsprings.So for genetic improvement, best Sire should be used.
3.The hybrid offsprings carry the recessive alleles too which will result in deteriotion of production in next generation.
4.Hybrids don't breed true,they can't produce offsprings of their own kind.
5.In plant breeding:- quality is compromised over quantity. The hybrid plants loss quality and taste.
6.So use hybrids for one generation and that too with proper selection. Otherwise instead of getting benefits we can face loss in terms of both quality and quantity. Hope it helps.
