1:23:01
Without parents?
1:23:02
Well, it has no father
because the egg was never fertilised.
1:23:07
No mother, because its genetic code
comes from another being.
1:23:11
Can you follow that?
1:23:13
And this creature
is an exact duplicate of itself?
1:23:19
Oh, Doctor, how can that be?
1:23:23
Come along.
1:23:30
Our experiments began with the simplest
of animals: shrimps and frogs.
1:23:36
Animals in which the female's eggs
are fertilised externally.
1:23:46
Then we moved on to mammals.
1:23:49
We tried several laboratory animals
and found the rabbit most convenient.
1:23:54
I had to develop instruments
which could accomplish the operation...
1:23:59
..and a whole micro-injection system.
I'll show you how it's done.
1:24:05
Here we are removing the eggs
of a white rabbit...
1:24:09
..from the Fallopian tubes.
1:24:13
Now you see the egg
under a microscope.
1:24:16
I have brought the point of an ordinary
sewing needle into view...
1:24:21
- ..to give an idea of the size.
- They are that small?
1:24:25
Most mammal eggs are about that size.
1:24:28
- Including human eggs?
- Yes.
1:24:30
The next step is to destroy
the egg nucleus...
1:24:35
..with ultraviolet light...
1:24:37
..so that none of its genetic makeup
remains.
1:24:43
Now you see an egg from a white rabbit...
1:24:46
..ready to be injected with the blood cell
from a black rabbit donor.
1:24:51
With the injection pipette...
1:24:54
..one of the blood cells is sucked up
and then injected into the egg.
