Meiosis, in fact, is the key process of sexual reproduction in eukaryotes, as it is the only shared and conserved feature of sex in eukaryotes. Meiosis originated early in eukaryotes, perhaps together with mitosis [9]. The cost of sex, thus, primarily applies to eukaryotes. Prokaryotes have ...

Such cells seem to give rise to diploid pollen grains in the following ways (i) When chiasmata are formed the i6 bivalents, 8 from each nucleus, are arranged on a common plate at the first metaphase. The rest of meiosis is, no doubt, completed in the normal way to give tetrads of...
where rare MOFs were observed in Wistar female rats that were exposed to ATZ during adulthood19. It was previously proposed that MOFs are formed as a result of the breakdown of incomplete oocyte cysts, which is a normal process63, or by the fusion of two distinct oocytes after birth64. Cys...
What process is called "one cell division", meiosis or mitosis? Describe the process of egg production in trematodes. Name the six steps of fertilization. What is the name given to the process in which a cell divides into two new daughter cells?
