What is the process of embryo splitting most accurately described as?

1. Combining two embryos into one

2. Dividing a single embryo into equal parts

3. Transferring embryos into other species

4. Stimulating embryo growth through hormones

The correct answer is: Dividing a single embryo into equal parts

The process of embryo splitting is most accurately described as dividing a single embryo into equal parts. This technique involves taking an early-stage embryo—usually at the blastocyst stage—and physically splitting it into two or more separate embryos, which can then develop into individual organisms. This method is often used in animal breeding to increase the number of offspring produced from a single fertilized egg, thus enhancing genetic material propagation and improving productivity in agricultural practices. By using embryo splitting, breeders can maximize the genetic potential of high-quality donor animals, allowing them to produce 'clones' or genetically similar offspring. This technique is distinct from combining embryos, transferring embryos across species, or stimulating growth via hormones, as those processes involve different biological mechanisms and objectives. In contrast, embryo splitting specifically focuses on replication of existing embryos, making option B the most accurate choice.
