Final answer:
Cells have a haploid amount of chromosomes/chromatids after both meiosis I and meiosis II, resulting in four haploid gametes each with half the amount of chromosomes present in a diploid cell.
Step-by-step explanation:
Cells have a haploid amount of chromosomes/chromatids after meiosis I and haploid amount of chromosomes/chromatids after meiosis II. Before meiosis I, DNA replication occurs, and each chromosome consists of two sister chromatids. Once meiosis I completes, these sister chromatids still stay together, but the homologous pairs of chromosomes have been separated into two new cells, which is why these cells are considered haploid. After meiosis II, the sister chromatids within each of the two daughter cells resulting from meiosis I are separated, leading to four haploid gametes. Each of these cells contains one set of chromosomes, which is half the amount of a diploid cell, and they no longer have sister chromatids linked together as the cells are now ready to develop into gametes. For example, in humans, a cell will contain 46 chromosomes (23 pairs) before meiosis I, but after meiosis I and II, each of the four resulting gametes will contain 23 individual chromosomes.
