Parthenogenesis

Features parthenogeneses Parthenogenesis parthenogenesis that is, until recently was regarded as one of the ways of sexual reproduction, such classification exists to this day the majority of textbooks. However, in light of what we know today about the essence of sexual reproduction, this view can not be maintained. Parthenogenesis is the emergence of an adult individual in the development process nonacceptance eggs. Thus, although the individual cells is gender, but does not obtain additional genetic information from the other parent. Parthenogeneses can be fully defined as sexual reproduction: it is something intermediate between sex and cyberspace way of issue of the offspring. For individuals in the process created parthenogeneses may have different genetic composition of the individual parent, if the ovum results from Mejia; haploid and are then formed as if in a time the sexual activity. We talk about the parthenogenesis haploid or automatically There are cases where individuals have a daughter the same genetic composition as the mothers body (when the ovum is produced mitotic way - that is, Appomattox parthenogenesis diploid, and some cases parthenogeneses haploid when haploid leukocyte are fertilized cinematic code).
