How do telophase I and telophase II differ during meiosis in animal cells?

a) Telophase I results in haploid cells, while telophase II results in diploid cells.
b) Telophase I involves the separation of homologous chromosomes, while telophase II involves the separation of sister chromatids.
c) Telophase I is the final stage of meiosis I, and telophase II is the final stage of meiosis II.
d) Telophase I and telophase II are identical processes with no differences.

Final answer:

Telophase I involves the separation of homologous chromosomes, resulting in two haploid cells, each with chromosomes that have two sister chromatids. Telophase II, on the other hand, involves the separation of sister chromatids into individual chromosomes, leading to four distinct haploid gametes.

Therefore, option b is correct

Step-by-step explanation:

The differences between Telophase I and Telophase II during meiosis in animal cells are crucial for understanding how haploid cells are produced. In Telophase I, which is the end of meiosis I, homologous chromosomes have been separated into two new cells; these cells are considered haploid because they contain one chromosome from each pair. However, each chromosome still consists of two sister chromatids. Cytokinesis typically follows, resulting in two haploid daughter cells ready to enter meiosis II.

During Telophase II, sister chromatids segregate into individual chromosomes and migrate to opposite poles, akin to what happens during mitosis. This phase marks the end of meiosis II and results in four unique haploid gametes that become sperm or eggs, depending on the sex of the organism. Contrary to one of the answer options offered, neither phase results in diploid cells. Therefore, the key difference is that Telophase I involves the separation of homologous chromosomes, whereas Telophase II involves the separation of sister chromatids.
