Immaculate Conception, or parthenogenesis is a modification of sexual reproduction, when the female gamete began to develop into a new individual without the participation of the male gamete to fertilize.Parthenogenetic reproduction is common in the animal kingdom, plants, and usually it increases the rate of reproduction.
parthenogenesis in animals and plants
Immaculate Conception is of two kinds - haploid and diploid parthenogenesis, depending on the number of chromosomes in the female gamete.Many insects, such as ants, wasps and bees, as a result of the first type having different breeding community of organisms.When haploid parthenogenesis, meiosis occurs and haploid gametes are created.From fertilized eggs can develop diploid females and haploid unfertilized egg develops fertile males.In the honeybee, for example, the queen lays the eggs are fertilized, which provide females (working individuals, the uterus), and unfertilized eggs, which give males (drones).Such a mechanism breeding insects plays an adaptive role, because it can regulate the appearance descendants depending on the type of gametes.
diploid parthenogenesis occurs in aphids.At the same time the female oocytes are exposed to a particular form of meiosis - chromosomes are not at odds, and turn into an egg without chromosomes are polar bodies.Development of the eggs carried in the mother's body, fully formed newborn female and hatch from eggs.This process goes on live births in several generations, until such time until a cell that contains one X chromosome and autosomes all.From it developed parthenogenetic male.The main advantage of partogeneneza to aphids - a rapid increase in the population because of its mature members can lay eggs.
«Immaculate Conception" in various forms is widespread in plants.One of them is called apomixis is parthenogenesis, simulating sexual reproduction.This form of conception occurs in certain flowering plants have diploid cell develops into an embryo without full participation of the male gametes.In other cases, there must be the pollen grain, stimulating parthenogenesis;pollen grain produces hormones necessary for the appearance of the embryo, and such cases are almost indistinguishable from sexual reproduction.
parthenogenesis people
forensic scientist is well known that at high temperatures, stress and extreme conditions of female egg can begin the process of division, even if it is not fertilized.It is believed that if a woman is ready to conceive, she can just warm up for a while in the bath, and the egg activates the process of transformation of the body, but most likely, it is not viable and will die soon.In
ready to fertilize the egg has 23 chromosomes that determine sex.
«Immaculate Conception" occurs when the mature female chromosomes are divided into two halves, forming 46 chromosomes in the egg cell required for the emergence of a new life.Then can begin the process of fragmentation and development of the embryo, but only females.
According to doctors, a human parthenogenesis occurs in the presence of the bacteria living in insects, but it can move into the human body, causing division of the egg and the formation of the embryo.The bacterium destroys the male germ or transform them into women.
lock in a lot of cases, when the floor of the human embryo has changed under the influence of extreme situations or in a hot climate, and the embryo is always changing male to female, in other words never happens.
Previously, this phenomenon is not heard at all.In any case, the word "parthenogenesis" appeared recently."Immaculate Conception" of Mary, Christians perceived as a miracle.And the fact that it could be a normal pregnancy, and no one had not occurred.
