Answer 2

Answer:

The correct option is (4), Metacentric

Explanation:

• The two arms of an isobrachial chromosome are equal in length where iso means equal and brachus means arm.
• Metacentric chromosome is usually isobrachial. Chromosomes with metacentric structures have a centromere in their center that divides the chromosome into two equal strands.
• E.g. 1st, 3rd, 16th, 19th and 20th chromosomes in humans are isobrachial(Metacentric chromosomes in nature)
