What are the 4 types of chromosomes?

What are the 4 types of chromosomes?

Chromosomes can be classified into 4 types based on the length of the chromosomal arms and the position of the centromere.

• Sub metacentric chromosomes.
• Acrocentric chromosomes.
• Telocentric chromosomes.
• Metacentric chromosomes.

What is the function of metacentric chromosome?

Metacentric. These are X-shaped chromosomes, with the centromere in the middle so that the two arms of the chromosomes are almost equal. A chromosome is metacentric if its two arms are roughly equal in length.

What do you mean by telocentric?

: having the centromere terminally situated so that there is only one chromosomal arm a telocentric chromosome.

What is telocentric chromosome Class 11?

The chromosome in which the centromere is located at one of the terminal ends is known as a telocentric chromosome.

What is the shape of Telocentric chromosome?

Centromere Positions The centromere of a telocentric chromosome is located at the terminal end of the chromosome, and p arms is barely visible. The shape of telocentric chromosome is similar to the letter “i” during anaphase.

What is the shape of telocentric chromosome?

What are Acrocentric and telocentric chromosomes?

A telocentric and an acrocentric chromosome differ from each other based on the position of the centromere. The telocentric chromosomes are present at the end or terminal of the chromosomes while the acrocentric chromosome is present between the center and the terminal, which is at the sub-terminal position.

What do you mean by telocentric chromosome?

A telocentric chromosome is a chromosome whose centromere is located at one end. The centromere is located very close to the end of the chromosome that the p arms would not, or barely, be visible. A chromosome that has a centromere closer to the end than the center is described as subtelocentric.
