What are the two main stages of meiosis?

The two main stages of meiosis are Meiosis I and Meiosis II, making this the correct choice.

Meiosis is a specialized form of cell division that reduces the chromosome number by half, resulting in the production of gametes—sperm and eggs in animals.

During Meiosis I, homologous chromosomes are separated into two daughter cells, leading to genetic variation through processes such as crossing over and independent assortment. This stage focuses on separating the homologous pairs, which is crucial for ensuring that gametes contain only one chromosome from each pair.

Meiosis II resembles mitosis, where the sister chromatids are finally separated. This stage ensures that each of the resulting gametes receives an equal and complete set of chromosomes.

The other choices do not accurately represent the stages of meiosis, as they either introduce incorrect stage labeling or do not exist in the context of cellular division. Meiosis I and II are recognized universally in biology and reflect the essential process by which gametes are formed.
