For example, there is human genetics, mouse genetics, fruit fly genetics, etc. So, do you know where genes are located?

Taxonomy – is the branch of biology that deals with identification, nomenclature and classification of an object. Cytology – is the branch of biology that deals with origin, structure and function of cell. So Cytotaxonomy presumably means the application of cytological data to taxonomy. More precisely we can say Cytotaxonomy …

In the 1870s, the observation that the nuclei of male and female reproductive cells undergo fusion in the process of fertilization leads to the decision that the cell nucleus plays a key role in inheritance. After that, when the cell is stained with the help of some when certain dyes …
