Question
Suppose a normal diploid cell contains 8 chromosomes, then there are _____
- 8 homologous pairs of chromosomes for every diploid cell.
- 8 chromatids for each diploid cell between S phase and the first division of meiosis.
- 4 chromosomes for each cell after meiosis I.
- Sperm cells made from the diploid cell would have 8 chromosomes.
Hint:
A diploid cell contains "2n" number of chromosomes.
The correct answer is: 4 chromosomes for each cell after meiosis I.
- A diploid cell contains "2n" number of chromosomes
- As given, there are 8 chromosomes, meaning 4 pairs of chromosome in the diploid cell
- In mitosis, the number of chromosomes will remain the same while the number of chromosomes will be reduced to half in the cells following meiosis
- Following meiosis, the number of chromosomes will reduce to half
- Hence, the number of chromosomes received by the dividing cells will be 4
