What occurs during anaphase 1?
Understand the Problem
The question is asking about the specific events that take place during anaphase 1 of meiosis, which is a key phase in the process of cell division that leads to the formation of gametes.
Answer
Homologous chromosomes separate and move to opposite ends of the cell.
During anaphase 1, homologous chromosomes separate and move to opposite ends of the cell, while sister chromatids remain attached at their centromeres.
Answer for screen readers
During anaphase 1, homologous chromosomes separate and move to opposite ends of the cell, while sister chromatids remain attached at their centromeres.
More Information
During anaphase 1 of meiosis, the homologous chromosomes are pulled apart to opposite poles of the cell, which is critical for reducing the chromosome number by half. This segregation allows for genetic diversity in the resulting gametes.
Tips
People often confuse anaphase 1 with anaphase 2. Remember, in anaphase 1, it is the homologous chromosomes that separate, while in anaphase 2, sister chromatids separate.
