Scelta multipla
In meiosis, which division is most similar to mitosis in terms of sister chromatid separation and maintenance of chromosome number per cell division?

B
Neither division; meiosis has no mitosis-like stages
C
Meiosis II
D

Guida verificata passo dopo passo1
Recall the key features of mitosis: during mitosis, sister chromatids separate, and the chromosome number per cell remains the same after division.
Analyze Meiosis I: homologous chromosomes separate, but sister chromatids remain together, resulting in a reduction of chromosome number by half.
Analyze Meiosis II: sister chromatids separate, similar to mitosis, and the chromosome number per cell remains the same after this division.
Compare Meiosis II to mitosis: both involve separation of sister chromatids and maintain chromosome number per cell division.
Conclude that Meiosis II is most similar to mitosis in terms of sister chromatid separation and chromosome number maintenance.
