What is the shape of chromosome? Give its names in the figure. |
|
Answer» Chromosomes are classified into four types by their shape in metaphase or in anaphase, which, in turn, is determined by the position of the centromere: i) Telocentric chromosomes: Rod-like and have a centromere situated on the proximal end. ii) Acrocentric chromosomes: Rod-like and have a small, or even imperceptible, arm. iii) Submetacentric chromosomes: Chromosomes having unequal arms are thus ‘L’ shaped. iv) Metacentric chromosomes: Having equal or almost equal arms and thus are ‘V’-shaped. |
