A normal metaphase chromosome with a midial centromere is ________?
Correct answer: A. Metacentric
- A. Metacentric
- B. Sub-metacentric
- C. Acrocentric
- D. Telocentric
Explanation
A chromosome with a centromere in the middle has two approximately equal arms and is called metacentric. A sub-metacentric chromosome has a slightly off-centre centromere, so students may select it if they overlook the word medial or middle.
