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. b) 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. d) scientists will be able to identify superior sets of dna sequences in sperm ensuring better yields of milk and meat.

The correct answer is D) Scientists will be able to identify superior sets of DNA sequences in sperm ensuring better yields of milk and meat.

Genome projects will contribute to better productivity in cattle in that scientists will be able to identify superior sets of DNA sequences in sperm ensuring better yields of milk and meat.

With the help of new technologies and nutrition discoveries, genome projects are improving the production of goods from cattle. The use of molecular genetic techniques in normal breeding of cattle has resulted in positive results. Two major categories of molecular makers had been identified, hybridization-based and polymerase chain reaction-based makers.  

An example of juxtacrine signaling is exemplified by the activity of some cell adhesion or ECM proteins, such as laminin, that do not just allow a cell to move over them, but act as signals to promote increased motility
