After meiosis I, the resultant daughter cells have:
same amount of DNA as in the parent cell in S phase
twice the amount of DNA in comparison to haploid gamete
same amount of DNA in comparison to haploid gamete
four times the amount of DNA in comparison to haploid gamete
During the S phase of the parent cell, DNA replication occurs, doubling the DNA content from 2C to 4C, while the chromosome number remains 2n . Meiosis I is a reduction division where homologous chromosomes separate, resulting in two daughter cells that are haploid (n) in chromosome number . However, since the sister chromatids have not yet separated (which happens in Meiosis II) , each chromosome still consists of two chromatids. Therefore, the DNA content in each daughter cell after Meiosis I is 2C (half of the parent's 4C). A final haploid gamete (formed after Meiosis II) has n chromosomes and 1C DNA content. Thus, the daughter cells after Meiosis I have twice the amount of DNA (2C) compared to a haploid gamete (1C).
