Assume that just five of those eggs can be made into healthy cloned embryos, two embryos are transferred to each surrogate mother, and one out of 100 embryos survives to birth (all reasonable assumptions based on animal data.)

Invertebrates (and higher animals) can also be placed in one of two groups based on how they develop as embryos.
