Maghasadásból

Maghasadásból is a term of Hungarian origin that translates to "from embryo splitting" or "from cleavage" in English. It refers to a process where a single embryo divides into two or more genetically identical individuals. This phenomenon is naturally observed in identical twins and higher-order multiples in various species.

In a biological context, maghasadásból describes the development of monozygotic twins, also known as identical twins. This occurs when a fertilized egg, the zygote, divides into two separate embryos early in development. Each of these embryos then develops into a complete individual, sharing nearly identical genetic material. The exact timing of this division can influence certain aspects of twin development, such as placental sharing.

Beyond natural occurrences, the concept of maghasadásból is also relevant in assisted reproductive technologies (ART), such as in vitro fertilization (IVF). Embryologists can intentionally split embryos in a laboratory setting to create more embryos for transfer or freezing. This technique, known as embryo splitting or blastomere separation, aims to increase the chances of pregnancy by providing multiple genetically identical embryos. However, the ethical implications and success rates of this procedure are subjects of ongoing discussion and research within the scientific and medical communities. The term highlights the origin of multiple individuals from a single cellular starting point.
