Embryo transfer technology (ETT) has revolutionized the breeding strategies in bovines as a tool to optimise the genetic improvement in cattle. What are benefits of using ETT?

1) It leads to a decrease in the number of offspring resulting in improved feed and nutrition to the existing offspring.

2) The offsprings born using this method will be free from diseases.

3) It is a potential tool in livestock transgenesis and diversity conservation.

Select the correct answer using the codes below.
