meiosis stages only
Term | Definition |
---|---|
Prophase I | Cell has 2n chromosomes Crossing over occurs |
Metaphase I | Chromosomes align in cell equator Spindle fibers attach to homologous pairs |
Anaphase I | Homologous pairs are separated One pair moves in each polar end of cell |
Telophase I | Chromosomes uncoil Cell divides along wquator |
Prophase II | Chromosomes still condense into chromatids Chromosomes condense |
Metaphase II | Spindle fibers attach to each chromatid Aligned at center of cell |
Anaphase II | Spindle fibers separate chromatids to opposite sides of cell |
Telophase II | Chromosomes condense nuclear membrane forms Cell divides in four haploid cells |
Meiosis | Process in sex cells where they divide in four haploid cells instead of two diploid cells |
