A version of the anti-abortion initiative soundly defeated by Colorado voters in 2008 is making its way to the 2010 ballot, this time reworked as an "egg-as-a-person" initiative. This new version would move the legal definition of a person further back into the reproductive cycle, granting cells the full spectrum of citizen rights. Opposition groups, including Colorado genetic and fertilization researchers, say the law would have spiraling consequences, that it would put women at risk and freeze current work in medicine and reproduction.
