Explanation / Answer

1. A. to separate homologous chromosomes

During meiosis I, each member of a pair of genes on homologous chromosomes tends to be randomly distributed into gametes independently of how other chromosomes are distributed. It results in giving all possible combinations in equal frequency. Independent assortment is characteristic of meiosis.

2. B. metaphase I

Independent assortment of homologous chromosomes occurs at metaphase I of meiosis I.
