• 
phase → Chromosomes 
, DNA = 2C
• 
Phase
After S phase, DNA is duplicated → DNA = 4C
Chromosome number does not change 
Chromosomes 
• Telophase I (after meiosis I)
Homologous chromosomes separate → Chromosome number halves 
Each nucleus still has two sister chromatids, so DNA 
• Telophase II (after meiosis II)
Sister chromatids separate → Chromosome number 
Each chromatid becomes an individual chromosome → DNA 
C
