A human is diploid with 2n = 46, a cell after meiosis I would contain how many chromosomes, homologous pairs, and chromatids? What about after meiosis II?

Final answer:

After meiosis I, each cell contains 23 chromosomes with no homologous pairs and each chromosome consists of two sister chromatids. Following meiosis II, there are four haploid daughter cells each with 23 single-stranded chromosomes.

Step-by-step explanation:

In humans, a diploid cell has a total of 46 chromosomes, comprising 22 pairs of autosomes and 1 pair of sex chromosomes. During the first division of meiosis, called meiosis I, homologous chromosomes separate, and each new cell contains one chromosome from each pair, resulting in two haploid cells. Each haploid cell has 23 chromosomes, and no homologous pairs (since the homologues have been separated), but each chromosome still consists of two sister chromatids. After meiosis II, the sister chromatids separate into individual chromosomes, creating a total of four haploid daughter cells, each with 23 chromosomes and no sister chromatids, as they've been divided.
