Sexual segregation is widespread in vertebrates (Ruckstuhl and Neuhaus 2005) and especially well researched in ungulates (Main and Coblentz 1996; Ruckstuhl and Neuhaus 2002; Bowyer 2004).Sexual segregation has been defined by some authors as the segregation of males and … WebCytoplasmic determinants are special molecules which play a very important role during oocyte maturation, in the female's ovary.During this period of time, some regions of the cytoplasm accumulate some of these cytoplasmic determinants, whose distribution is thus very heterogenic. They play a major role in the development of the embryo's organs. … opening square bracketCytoplasmic incompatibility (CI) is a phenomenon that results in sperm and eggs being unable to form viable offspring. The effect arises from changes in the gamete cells caused by intracellular parasites like Wolbachia, which infect a wide range of insect species. As the reproductive incompatibility is caused by bacteria that reside in the cytoplasm of the host cells, it is referred to as cytoplasmic incompatibility. In 1971, Janice Yen and A.

Each human cell contains around two metres of DNA, which must be tightly folded to fit inside the cell nucleus. However, in order for the cell to function, proteins must be able to access the sequence information contained within the DNA, in spite of its tightly-packed nature. Hence, the cell has a number of mechanisms in place to control how DNA is organized. Moreover, nuclear organization can play a role in establishing cell identity. Cells within an organ…
