Y-chromosome is _________?
Correct answer: A. Acrocentric
- A. Acrocentric
- B. Telocentric
- C. Submetacentric
- D. Acentric
Explanation
The human Y chromosome is generally classified as acrocentric because its centromere lies close to one end, producing one very short arm and one long arm. Students may choose telocentric because the centromere appears very near the end, but a true telocentric chromosome has the centromere at the terminal end, which the human Y chromosome does not.
