At the end of meiosis I the two cells are already haploid because each pole holds:
ABoth copies of every pair
BOne of each homologous pair
COnly maternal chromosomes
DOnly paternal chromosomes
Answer & Solution
Correct answer: B. One of each homologous pair
1. Ploidy counts chromosome sets, not chromatids.
2. The cells are haploid because at each pole there is just one of each pair of the homologous chromosomes.
3. Therefore only one full set of the chromosomes is present.
4. Each homolog still consists of two sister chromatids, which is why the cells can look diploid at a glance.
