This gets more and more difficult to pull off as the number gets more and more different. The other kind of cell, located in the testicles, forms the sperm. A hybrid species can be created if the animals have the same genetic makeup. This will help reduce their exposure to diseases from other animals. Still, it didnt work as well as simply killing them. In the lab, its now possible to create whats called a germ-line chimera. Such an animal has two kinds of cells, each with its own DNA. A small amount of alcohol is needed to get a small dog drunk.
