Multiple Choice

Which statement correctly describes the chromosomes in each daughter cell at the end of meiosis I?

Each daughter cell contains a complete set of homologous chromosomes, identical to the parent cell.

Each daughter cell contains half the number of chromosomes, and all chromosomes are single chromatids.

Each daughter cell contains one chromosome from each homologous pair, and the chromosomes are still composed of two sister chromatids.

Each daughter cell contains two chromosomes from each homologous pair, and the chromosomes are single chromatids.

Verified step by step guidance

Recall that meiosis I is the first division in meiosis, where homologous chromosomes are separated into two daughter cells.

Understand that before meiosis I, DNA replication has already occurred, so each chromosome consists of two sister chromatids joined at the centromere.

Recognize that during meiosis I, homologous chromosome pairs (each consisting of two sister chromatids) are separated, so each daughter cell receives one chromosome from each homologous pair.

Note that because sister chromatids remain attached during meiosis I, the chromosomes in each daughter cell are still composed of two chromatids.

Therefore, at the end of meiosis I, each daughter cell contains half the number of chromosomes (haploid), but each chromosome still consists of two sister chromatids.
