What happens to chromosomes during the first four stages of meiosis, known as meiosis I?
Prophase I – chromosomes begin to condense, homologous chromosomes pair, and crossing over occurs Metaphase I – spindel fibers attach to chromosomes as the chromosomes line up along the middle of the cell Anaphase I – chromosomes start moving to the opposite ends of the cell as the spindle fibers shorten Telephase I – chromosomes reach the opposite ends of the cell as the nuclear membrane forms
