Answer: two
Each primary oocyte divides twice in meiosis unequally in each case. The first division produces a daughter cell and a much smaller polar body which may or may not …
The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically …
The concept of the Hayflick limit was advanced by American anatomist Leonard Hayflick in 1961 at the Wistar Institute in Philadelphia Pennsylvania United States.Hayflick demonstrated that a normal human fetal cell population will divide between 40 and 60 times in cell culture before entering a senescence phase. This finding refuted the contention by French Nobel laureate Alexis Carrel that …
An asymmetric cell division produces two daughter cells with different cellular fates. This is in contrast to symmetric cell divisions which give rise to daughter cells of equivalent fates. Notably stem cells divide asymmetrically to give rise to two distinct daughter cells : one copy of the original stem cell as well as a second daughter programmed to differentiate into a non-stem cell fate.
8-cell embryo at 3 days The beginning of the cleavage process is marked when the zygote divides through mitosis into two cells. This mit…
