Across the entire meiosis process, DNA is replicated
Atwice, once before each meiotic division
Bonce, before Meiosis I
Cnever; meiosis just sorts existing DNA
Dfour times, once per daughter cell
Answer & Solution
Correct answer: B. once, before Meiosis I
A single S phase before Meiosis I copies the DNA from 2C to 4C. Two divisions then halve it: 4C → 2C after Meiosis I → 1C after Meiosis II. This single-copy-double-divide pattern is why chromosome count halves.
