“A Human Parthenogenetic Chimera”, Lisa Strain, Jon P. Warner, Thomas Johnston, David T. Bonthron1995-10-01 (cloning)⁠:

In mice, parthenogenetic embryos die at the early post-implantation stage as a result of developmental requirements for paternally imprinted genes, particularly for formation of extra-embryonic tissues. Chimeric parthenogenetic ↔︎ normal mice are viable, however, due to non-random differences in distribution of their 2 cell types.

Species differences in imprinting patterns in embryo and extra-embryonic tissues mean that there are uncertainties in extrapolating these experimental studies to humans.

Here, however, we demonstrate that parthenogenetic chimerism can indeed result in viable human offspring, and:

suggest possible mechanisms of origin for this presumably rare event.
