Four chromosomes were observed at mitosis in haploid as well as diploid strains and four bivalents were observed at meiosis in the diploid. Therefore it is assumed that a) the haploid number of chromosomes inH.wingeiis four and b) somatic pairing occurs in the diploid.Marjorie Crandall...
During interphase, chromosomes are not distinctly visible as they are in the form of chromatin, which is less condensed. - Prophase: In this phase, chromosomes begin to condense and become visible. However, they are still not as distinct as they will be later. - Metaphase: During metaphase,...
If the number of bivalents are 8 in metaphase - I, what shall be the number of chromosomes in daughter cells after meiosis -I and meiosis -II respectively:- View Solution A: Mitosis is a equational division . R:During mitosis the number of chromosomes is reduced to a half. ...
Aneuploidy, any deviation from an exact multiple of the haploid number of chromosomes, is a common occurrence in cancer and represents the most frequent chromosomal disorder in newborns. Eukaryotes have evolved mechanisms to assure the fidelity of chromosome segregation during cell division that include...

In humans, the diploid number of chromosomes is 46, including the sex-determining X and Y chromosomes. Meiosis involves a single round of DNA replication, but two rounds of cell division; the products (spermatozoa or an oocyte) contain the haploid number of chromosomes (23 in humans). ...

produced rather than two. Since the number of chromosomes is halved with each division, each daughter cell has just a single set of chromosomes and is called ahaploidcell. During reproduction, the union of a female gamete with a male gamete restores the two full sets of chromosomes in a ...

Mitosis is the process where a parent cell divides into two daughter cells and each receives an exact copy and number of the chromosomes (genetic material) and is called as equational division. It maintains cell growth and repair. History ...
