Centromeric index
From WikiLectures
Centromeric index is a value used in cytogenetics when describing chromosomes. It is calculated according to the position of the centromere as the ratio of the length of the short arm p to the length of the entire chromosome p+q. Based on this value, we divide chromosomes into metacentric, submetacentric, acrocentric, etc.
| centromeric index
p/(p+q) |
chromosome type |
|---|---|
| 0,5–0,39 | metacentric |
| 0,38–0,26 | submetacentric |
| 0,25–0,13 | acrocentric |
| 0,12-0 | telocentric |
