Final answer:
Chromosomes are classified into 4 types based on their centromere location: Metacentric, Submetacentric, Acrocentric, and Telocentric.
Step-by-step explanation:
Chromosomes are classified into 4 types based on their centromere location: 1. Metacentric (the centromere is near the middle); 2. Submetacentric (the centromere is slightly off center); 3. Acrocentric (the centromere is closer to the end than to the center); and 4. Telocentric (the centromere is at one end).
