Types of Chromosomes:
Types of chromosomes can be easily identified during cell division.
1. Metacentric :
The centromere is exactly at the mid-point in this chromosome, therefore chromosome looks like the English letter ‘V’.
The arms of this chromosome are equal in length.
2. Sub-metacentric :
The centromere is somewhere near the mid-point in this chromosome. It’s looks like English letter ‘L’.
One arm is slightly shorter than the other.
3. Acrocentric :
The centromere is near one end of this chromosome which looks like the English letter ‘j’.
One arm is much smaller than other.
16.1
4. Telocentric :
The centromere is right at the end of this chromosome making the chromosome look like the English letter ‘i’.
This chromosome consists of only one arm.
