Answer 2

"Acrocentric - chromosome arms are identical in size" - this statement is incorrect (Option - A)

• Chromosomes are mostly of 4 types on the basis of the size of their chromatids.
• Metacentric - the word itself suggests located in the middle, i.e. the centromere is located in the middle - such that both the sections on either side of the centromere are of equal length. - V-shaped
• Sub-metacentric - such chromosomes show asymmetry as the length of arms on both sides of the centromere is not equal.
• Acrocentric - The arms of such chromosomes are highly asymmetric leading to 1 very long and 1 very short section. The centromere is located away from the center.
• Telocentric - Telo means tale or end, hence, the centromere is located at the end and chromatids are present only on one side of the centromere.
