WebHaploid mammalian parthenotes have compromised developmental competence compared with diploid parthenotes (Henery & Kaufman 1992, Kawarsky et al. 1996, Kim et al. 1997a, Liu et al. 2002). Therefore, for precise comparison of the development of parthenotes and fertilized embryos or diploid androgenotes, diploid parthenotes are needed. Webparthenotes are still unclear, one persuasive explanation is that the functions of the male and female genomes are definitively different as a result of epigenetic modifications that occur during gametogenesis (Monk, 1988; Surani et al., 1990; Sasaki et al., 1992; Brannan and Bartolomei, 1999). This hypothesis is supported by our recent ...
