- Number of centromeres
- Position of centromeres
Types of chromosome on the basis of number of Centromeres
|Type||Number of cetromeres|
|Holocentric||Diffused (Here, microtubules are attached along the length of chromosome)|
Types of chromosome on the basis of position of centromere
|Type||Position of Centromere||Shape||Details||Examples|
|Metacentric||Centre (median)||v-shaped||equal arms||tradescantia, amphibians|
|Sub-metacentric||Near centre (sub-median)||J or L shaped||Two unequal arms||human being|
|Acrocentric||Near at one end (sub-terminal)||One arm very short and another long||grasshopper|
