The cell division occurs in two forms, namely mitosis, which occurs in somatic cells to increase the mass and size of an individual, while meiosis occurs in sex cells to form gametes.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this ...
Does synapsis occur in meiosis?Meiosis:Meiosis is a kind of cell division which is used to produce egg cells and sperm cells. It begins with cells which have two copies of each gene and produces cells which have a single copy of each gene....
In What Type of Cells Does Mitosis Occur? Most of the cell division taking place in living organisms happens in somatic (non-reproductive) cells through mitosis. For instance, the human body sheds and replaces up to 40,000 skin cells per day, according to theAmerican Academy of Dermatology....
Can growth occur only through mitosis? The Purpose of the Reproduction Both sexual and asexual organisms go through the process of mitosis. It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproductio...
The experiment may suggest that modification does not occur in embryonic stem cells, but other effects of heat– shock on CI could also explain the results, and no apparent reductions in bacterial infection levels were observed. Clearly, more experiments on timing of sperm modification are needed....

Mistakes duringmitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans....
(known as drive) allows a rapid increase in B chromosome frequency in natural populations. Drive mechanisms can operate before, during or after meiosis14, but how the alteration of cell division is controlled by the B chromosome is mostly unknown15. In rye, the nondisjunction of the B ...
Higher-level multicellular organisms, such as humans, are composed of trillions of cells, cells being the fundamental units of life. The nucleus within a cell houses our DNA, which contains the instructions for the structure and functioning of a cell. The DNA is packaged as chromatin, where it...
