Multiple Choice
Which phase of meiosis is responsible for separating homologous chromosomes (not sister chromatids) to opposite poles of the cell?
A
Anaphase II
B
Anaphase I
C
Telophase I
D
Metaphase I
Verified step by step guidance1
Recall that meiosis consists of two sequential divisions: meiosis I and meiosis II, each with its own phases (prophase, metaphase, anaphase, telophase).
Understand that homologous chromosomes are pairs of chromosomes (one from each parent) that pair up during meiosis I, while sister chromatids are identical copies formed during DNA replication.
Identify that the separation of homologous chromosomes occurs during anaphase of meiosis I, where each homolog is pulled to opposite poles of the cell.
Recognize that anaphase II is when sister chromatids separate, not homologous chromosomes.
Therefore, the phase responsible for separating homologous chromosomes to opposite poles is Anaphase I.
