Guida verificata passo dopo passo1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.
Recall that meiosis consists of two consecutive divisions: Meiosis I and Meiosis II. Each division has several phases: Prophase, Metaphase, Anaphase, and Telophase.
Focus on Meiosis I, where homologous chromosomes (each consisting of two sister chromatids) pair up and then separate.
During Anaphase I, the homologous chromosomes are pulled apart to opposite poles of the cell. This is the key event that distinguishes Anaphase I from other phases.
Recognize that the separation of homologous chromosomes during Anaphase I reduces the chromosome number by half, which is a critical step in forming haploid cells.
