5.1 Meiosis
Notes
Meiosis makes haploid gametes from a diploid cell: one DNA replication, two divisions.
- Meiosis I: homologous chromosomes separate (reduction division).
- Meiosis II: sister chromatids separate.
- Result: four genetically different haploid cells.
Practice
A human cell with 46 chromosomes makes gametes with:
Haploid.
Homologous chromosomes separate in:
Reduction division.
Meiosis differs from mitosis because meiosis:
Gametes.
