Actually, this works with any two eggs (provided they're not deficient). This is beause the only thing that differs from a gamete and a human being that is not quantitative is the sexual chromoses. You *absolutely* need an X. Since in half of the spermatozoids, there is no X, half of them are unable to reproduce. There are other problems that stops two X spermatozoids (or one X and one Y) from making a successful embryo. I have not yet read any article on fusing the information then implementing it in an ennuclied ova.
That is correct, which is why I used 'two eggs' as an example, as opposed to 'two sperms'.
Statistical clarification:
Assuming that a sperm has equal chances of being X / Y, there is a 75% chance for two sperms to contain sufficient genetic information for a human.
Two eggs always (100% chance) contain sufficient information.
Other restrictions:
Two eggs will never yield a male.
A proper cellular structure (e.g. that of an egg) is required. This is an additional requirement in the case of two sperms.
For both sperm+sperm and egg+egg, there is a notable lack of built-in mechanism for the introduction of genetic material into each other.
Here is a thought experiment:
Suppose we have invented a device that can hold exactly two gametes inside. The device is designed to always take the genetic material of one gamete and stick it into the other 1 minute after both gametes have been placed inside. There is no way to get the cells out after they have been put inside. Cells cannot die inside the device.
If fertilization was successful, the resulting cell is immediately transferred to a viable womb-like environment.
We have also invented a second device. When a female presses the button on this device, the (viable) egg she currently has in her body will be magically teleported into the first device.
Two questions:
1)
Suppose 50% of the females (Group A) are hypnotized from birth to always press the button whenever they have a viable egg. There is no way to break the hypnosis.
The other 50% (Group B) will never press the button, but are free to procreate normally (i.e. by having sex with a male).
Are the eggs of Group A any more 'human' than those of Group B?
2)
(this is essentially the other abortion thread, about 'abortion to save mother')
Suppose that pressing the button on the second machine will kill the female.
Is it 'right' to not press the button?
