Concatenated embryos The larvae cut into 2 equal parts and apply to transfer to the receiver. Be able to produce identical twins, the second from a single embryo. In embryo splitting requires specialized tools to perform is a micromanipulator. And use very thin glass pipette (holding pipette) to suction embryo. Then use a small needle (Microneedle) to divide the embryo. Alternatively, use a small knife (microblade) to cut.
