During which phase of Meiosis I do homologous chromosomes separate?
A
Telophase I
B
Anaphase I
C
Prophase I
D
Metaphase I
Verified step by step guidance1
Understand that Meiosis I is the first division in meiosis, which reduces the chromosome number by half and involves the separation of homologous chromosomes.
Recall the stages of Meiosis I: Prophase I, Metaphase I, Anaphase I, and Telophase I.
In Prophase I, homologous chromosomes pair up and exchange genetic material through crossing over, but they do not separate.
In Metaphase I, homologous chromosomes align at the metaphase plate, but they are still paired together.
In Anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell, which is the phase where their separation occurs.
