After meiosis I, the resultant daughter cells have:

A

same amount of DNA as in the parent cell in S phase

B

twice the amount of DNA in comparison to haploid gamete

C

same amount of DNA in comparison to haploid gamete

D

four times the amount of DNA in comparison to haploid gamete

Step-by-Step Solution

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).
