> If two cells, each one of which contains an embryo bee, are knocked into one, the two bees are consolidated, and the result is a now bee double the usual size.

QUOTED MATERIAL:

The first chimeric animals were created by researchers in the 1960s, when experiments with mouse embryos showed they could combine to form a single mouse of normal size. 

Scientists at the Oregon National Primate Research Centre produced animals, known as chimeras, by sticking together between three and six rhesus monkey embryos in the early stages of their development.

In a series of experiments, researchers found it impossible to create chimeric monkeys by injecting stem cells into early stage embryos. Only when very young embryos were merged together could they make chimeric animals.

"The macaque embryonic stem cells tested were unable to mix in with cells of the host embryos. This may be reassuring to those who worry that human embryonic stem cells could be used to make chimeric people, although in itself this should not be a concern, as such rare individuals already exist from the spontaneous merger of two early embryos."
