Science's discovery that fatherless children are possible in the future.
As a first step, Chinese scientists have succeeded in producing fatherless mice.
In nature, birds, lizards, snakes, and many species of fish, including sharks, produce offspring without the aid of a father through the so-called 'virgin birth' pathogenesis.
But this is the first time this has been possible in the laboratory.
Chinese scientists have succeeded in making a virgin birth possible without the help of male genetic DNA.
Virgin reproduction has not yet been possible in mammals because of the lack of a genomic imprint that dictates which part of the parents' genetic makeup should be active in infants.
Yancheng Wei and colleagues at Shanghai Jiao Tong University have shown that virgin birth is possible in mammals as well.
This is possible by modifying the DNA and modifying the genetic activity.
They modified the genetic records of seven important regions that influence sperm in the adult egg.
The transplanted ovum was then deposited in the female mice.
The mice then passed through natural pregnancies and were born.
Thus, only one of the mice, which was born without male help by Chinese scientists, reached maturity.
This result also shows the need for more research to be done in the field.
It is considered a great achievement of the scientific world to be able to artificially modify the ovum and develop it into an embryo without the intervention of male sperm.
Chinese researchers point out that the same technology could be used in a wide variety of fields, including agriculture and medicine, with the success of experiments in mammals.
The process of ovulation without male sperm is commonly found in small organisms such as ants, wasps and bees.
But such methods are not natural in more complex mammals.
Research on the scientific achievements of Chinese researchers has been published in full in the Journal of Proceedings of the National Academy of Sciences.
