How will genome projects contribute to better productivity in cattle?

A Genes from animals with better yields can be complementarily paired with the existing genes of the animal.Genes from animals with better yields can be complementarily paired with the existing genes of the animal.
B The less vigorous set of genes can be replaced by their more vigorous counterparts in the animal’s genome.The less vigorous set of genes can be replaced by their more vigorous counterparts in the animal’s genome.
C Scientists will be able to introduce genes from different species of animals into cattle to improve fertility.Scientists will be able to introduce genes from different species of animals into cattle to improve fertility.
D Scientists will be able to identify superior sets of DNA sequences in sperm ensuring better yields of milk and meat.

Genome projects can identify specific genes associated with higher productivity in cattle, such as increased milk production or faster growth rates. By understanding the genetic makeup of individual animals, scientists can selectively breed cattle with desirable traits, leading to better productivity in terms of meat and milk production. This targeted breeding can help to improve overall herd productivity and efficiency.
