Surely each of you knows the story describedin Scripture. Mary, being the chosen one of God, brought forth an immaculately conceived child. Whether it really happened or was just the result of the wild imagination of the authors of those times, today it is difficult to say. But let it be known to you, the immaculate conception in our world is quite a common thing. What is parthenogenesis and what is its essence?
Perhaps, to one of the greatest mysteries of ourthe universe can be attributed precisely the birth of life. Where did it come from and who is the creator of everything and everything - the secret sealed. But whoever our creator was, he took great care to ensure that life on the blue planet never dried out. Its various forms inhabiting the Earth are capable of reproducing themselves similar in the most diverse, sometimes very unexpected ways.
What is parthenogenesis?This is the ability of the female to give birth to a new generation without the participation of the sexual partner - the male. This does not mean that males are not needed at all, they, of course, are important. Parthenogenesis is not asexual reproduction method, like in some plants (budding, for example). But if it happens so that the female individual for some reason could not find a partner for mating and fertilization of the egg did not happen, she can still produce full-fledged offspring into the world without his participation. This ability provides the mind with a very good survival rate. When the number falls, females in a short time can fill the population and continue the race. That is the essence of parthenogenesis.
Another important feature of this breeding -regulation of the ratio of the number of females and males. So, for example, bees from unfertilized eggs appear drones (males), and from fertilized - working individuals, which are all female.
What is parthenogenesis and how can it occur incertain animals? In some species, it is considered the main method of reproduction (obligate). For other forms, it is cyclic, that is, the offspring periodically appears from unfertilized eggs, but more often with the participation of the male. The optional, or emergency mode of reproduction provides the species with survival in the most difficult life conditions, this is the essence of parthenogenesis for them. These cases are rather the exception, because usually such animals adhere to bisexual reproduction.
Что такое партеногенез?This is a process in which the parent egg, being unfertilized, begins to develop, to subsequently become a full-grown adult. Parthenogenesis can vary significantly between species. So, for example, reproduction by bees parthenogenesis is significantly different from the reproduction of other insects, say, ants.
Knowledge of what parthenogenesis is and how it isoccurs, greatly influenced the development of science and gave impetus to the emergence of some areas in the industry. Thus, scientists have learned that parthenogenesis in the silkworm is triggered after exposure to certain temperatures. This greatly accelerated the breeding of these insects.
What is the essence of parthenogenesis is well known.beekeepers and silk producers, many invertebrates use just such a method. The immaculate conception is often practiced by some species of lizards, fish, the process is well known to representatives of the plant world, there is even parthenogenetic turkey.
Representatives of science are working on studying thisfeatures, tirelessly. Many attempts have been made to start parthenogenesis in warm-blooded animals. Unfortunately, it is impossible to cite examples, since in some cells the growth of cells and the development of embryos took place, but it never came to the final stage. From the side of medicine interest is also caused considerable. A survey was conducted, after which it became known that the majority of married couples who cannot have a baby would gladly decide on such an immaculate conception. Who knows, perhaps, in time, the veil of secrecy will be ajar. And the miracle will become a reality - parthenogenesis can give life to a human baby.
