In this article we will discuss about the two parts of cell division: 1. Mitosis 2. Meiosis. The process in which a cell divides to form two new cells, each containing a nucleus, is called cell division. It is of two types i.e., mitosis and meiosis. In mitosis, which is also called vegetative cell division, the chromosomes in the nucleus [...]
In this article we will discuss about some cytological slides and specimen. 1. B-Chromosome or Supernumerary Chromosome: i. The nuclei of some animals or plants contain one or more chromosomes in addition to normal chromosomes. These additional chromosomes are called B-chromosomes or supernumerary chromosomes. ii. First described by Wilson in 1905 in Metapodius, an insect, these chromosomes have now been [...]
