Understandings:
• One diploid nucleus divides by meiosis to produce four haploid nuclei
• Separation of pairs of homologous chromosomes in the first meiotic division halve the chromosome number
Meiosis is the process by which sex cells (gametes) are made in the reproductive organs
- It involves the reduction division of a diploid germline cell into four genetically distinct haploid nuclei
The process of meiosis consists of two cellular divisions:
- The first meiotic division separates pairs of homologous chromosomes to halve the chromosome number (diploid → haploid)
- The second meiotic division separates sister chromatids (created by the replication of DNA during interphase)
