Anaphase I and anaphase II differ mainly in what is being pulled apart and what kind of cells they produce in meiosis.

Core difference (one-line)

  • Anaphase I: homologous chromosome pairs separate.
  • Anaphase II: sister chromatids separate.

Feature Anaphase I (Meiosis I) Anaphase II (Meiosis II)
What separates? Homologous chromosomes (each still made of two sister chromatids) move to opposite poles.Sister chromatids of each chromosome split at the centromere and move to opposite poles.
Chromosome number effect Reduces chromosome number from diploid to haploid (reduction division).Keeps chromosome number haploid but changes duplicated chromosomes into single-chromatid chromosomes.
Centromere status Centromeres do not split; sister chromatids stay attached.Centromeres split; sister chromatids separate.
Outcome per starting cell Two haploid cells, each with duplicated chromosomes.Four haploid cells total (from the original meiosis), each with unduplicated chromosomes.
Similarity to mitosis Unique to meiosis; no exact mitotic equivalent because homologous pairs separate.Very similar to mitotic anaphase, where sister chromatids separate.

Simple story to remember it

Imagine a pair of similar shoes from two parents:

  • In anaphase I, the “parent pairs” get split: one shoe from mum goes to one side, one from dad to the other side (homologous chromosomes separate).
  • In anaphase II, each individual shoe’s laces are undone so the left and right halves are pulled apart (sister chromatids separate).

So, anaphase I = split the pairs , anaphase II = split the copies.
