Verified step by step guidance

Understand the concept of independent assortment: Independent assortment refers to the random distribution of maternal and paternal chromosomes into gametes during meiosis. This process contributes to genetic diversity.

Review the stages of meiosis: Meiosis consists of two stages, meiosis I and meiosis II. Meiosis I is where homologous chromosomes are separated, and meiosis II is where sister chromatids are separated.

Identify when homologous chromosomes are separated: Independent assortment occurs during the separation of homologous chromosomes, which happens in meiosis I during metaphase I and anaphase I.

Differentiate between meiosis I and meiosis II: In meiosis I, homologous chromosomes line up and are separated, allowing for independent assortment. In meiosis II, sister chromatids are separated, which does not involve independent assortment.

Conclude that independent assortment occurs in meiosis I only: Based on the understanding that independent assortment involves the separation of homologous chromosomes, it is clear that this process occurs during meiosis I.
