Verified step by step guidance1
Step 1: Understand the starting point of meiosis, which is a diploid germ cell containing two sets of chromosomes (2n).
Step 2: Recall that meiosis consists of two consecutive divisions: meiosis I and meiosis II, which reduce the chromosome number by half and separate homologous chromosomes and sister chromatids.
Step 3: Recognize that meiosis I separates homologous chromosomes, resulting in two haploid cells (n), each with chromosomes consisting of sister chromatids.
Step 4: Understand that meiosis II separates sister chromatids, producing four haploid cells, each genetically distinct due to crossing over and independent assortment.
Step 5: Conclude that the final product of meiosis from one diploid germ cell is four genetically distinct haploid cells, which are gametes.
