If a cell has $2n = 20$ chromosomes at the G1 phase, what will be the number of chromosomes and DNA content in each daughter cell after the completion of meiosis I?
- A. chromosomes and DNA content
- B. chromosomes and DNA content
- C. chromosomes and DNA content
- D. chromosomes and DNA content
Show correct answer & step-by-step solution
Correct answer: A — chromosomes and DNA content
Solution
- The initial cell has $2n = 20$ chromosomes and DNA content after S phase.
- Meiosis I is a reductional division that separates homologous chromosomes.
- Each daughter cell receives chromosomes.
- Since sister chromatids remain attached, the DNA content per cell is .
- Hence the answer is (A).
