sim Posted September 5, 2008 Share Posted September 5, 2008 can an egg cell only be fertilized and start dividing by a sperm cell? Link to comment Share on other sites More sharing options...
insane_alien Posted September 5, 2008 Share Posted September 5, 2008 generally yes. although some species have evolved so that the female can fertilise her own egg and the species has done away with the males IIRC. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted September 5, 2008 Share Posted September 5, 2008 A frog egg can be "fertilized" by poking it with a needle. Link to comment Share on other sites More sharing options...
sim Posted September 5, 2008 Author Share Posted September 5, 2008 lol i was talking about the human female egg cells - only sperm can fertilize them right? Link to comment Share on other sites More sharing options...
Mr Skeptic Posted September 5, 2008 Share Posted September 5, 2008 lol i was talking about the human female egg cells - only sperm can fertilize them right? That's by far the easiest, cheapest, funnest, and most effective way to do it. Link to comment Share on other sites More sharing options...
sim Posted September 6, 2008 Author Share Posted September 6, 2008 lol sure it is so your sure it is just sperms? Link to comment Share on other sites More sharing options...
Mr Skeptic Posted September 6, 2008 Share Posted September 6, 2008 You can also do it clone style. Cut out the egg's nucleus, and insert the nucleus from an adult cell. I think they need to zap it to make it think it's been fertilized. It's much more trouble, seems to carry risks of abnormal development, and has a terribly poor success rate (think less than 1%).

Mostly because of problems with genomic imprinting. I don't think there are any human parthenotes in existence, most of the research has been carried out in animal models.
