Answer
|
Feature |
Anaphase I |
Anaphase II |
|
What separates |
Homologous chromosomes (bivalents) |
Sister chromatids |
|
Centromere behavior |
Remains intact; chromosomes move as units |
Splits; chromatids separate |
|
Chromosome number |
Reduced from 2n to n (reductional) |
Remains n (equational) |
|
Result |
Haploid cells with duplicated chromosomes |
Haploid cells with single chromatids |
Key Point: Anaphase I is unique to meiosis and is the reductional step that halves chromosome number.
