overwintering stage of zygote

A zygote is the union of the sperm cell and the egg cell. Multicellular organisms produce Gametes which fused by the process of Fertilization resulting in Zygotes formation. A zygote is the cell formed when two gametes fuse during fertilization.The DNA material from the two cells is combined in the resulting zygote. In the spring meiotic division occurs and produces a multinucleate structure (haploid nuclei). When these two haploid cells join, they form a single diploid cell that contains a total of 46 chromosomes. ... Zygote may represent "overwintering stage" in life cycle of an organism. During the spring season, meiotic divisions occur in it and a multinucleate structure is formed.

Zygotene definition is - the stage of meiotic prophase which immediately follows the leptotene and during which synapsis of homologous chromosomes occurs. In early stages of the 3PN zygote development, cellular cleavage is likely to be normal, with arrested development or aneuploidy occurring at a later development stage (3). The second period of development lasts from two weeks after conception through the eighth week, during which time the organism is known as an embryo. At the ninth week post-conception, the fetal period begins. 14 Important Science Questions Not all zygotes make it to the next stage of prenatal development, however. In these, zygote secretes a wall around itself during winters. The cellular mechanisms present in the gametes also function in the zygote, but the newly fused DNA produces a different effect in the new cell. Once a single sperm has broken through the outer surface, chemical changes in the surface of the egg prevent other sperm from entering.1 This … Thank you, {{form.email}}, for signing up. During an IUI, semen is inserted into the uterus using a catheter so that fertilization takes place inside the woman's body.
