THE EXAMS POINTMitosis and meiosis at a glance
Begin at the centre. Explore a branch, explain its connection, then test your recall. Tap any branch heading to fold or expand it.
In recall mode, focus or tap a branch to reveal its explanation. Branches group related ideas; they do not imply a chronological sequence.
Mitosis and meiosis at a glance
01 · Mitosis
One nuclear division; usually two daughter cells. Chromosome-set number is generally maintained.
02 · Meiosis
Two nuclear divisions after one DNA replication; usually four haploid products from a diploid precursor.
03 · Key separation
Mitosis: sister chromatids. Meiosis I: homologous chromosomes. Meiosis II: sister chromatids.
04 · Genetic variation
Crossing over and independent assortment during meiosis contribute to variation.
Connect the branches
The first meiotic division is reductional because homologous chromosomes separate.
Avoid the exam trap
There is no second S phase between meiosis I and meiosis II.
Test yourself: What separates at anaphase I?
Homologous chromosomes separate; sister chromatids remain joined until meiosis II.
A concise revision aid with simplified connections. It supports the full chapter and primary references; it does not replace them.
