parthenogenetic chimera

genetics

Quick Summary

A chimera is an organism or tissue containing at least two different sets of DNA, typically from the fusion of multiple zygotes (fertilized eggs). This differs from mosaics, which have cells originating from a single zygote, and hybrids, which result from crossing different species.1

Parthenogenetic chimeras can form when an egg produced through parthenogenesis (development without fertilization) fuses with a normal zygote. Parthenogenesis is a reproductive strategy where a female gamete develops without fertilization, common in many invertebrates and lower plants. While typically limited to lower organisms, experimental mammalian parthenogenetic chimeras have been created.12
