When do sister chromatid separate during meiosis?
The sister chromatid separate during anaphase II in meiosis. During anaphase I homologous chromosomes get separated.
During meiosis, when do the chromosomes line up as homologous pairs?
During meiosis, chromosomes line up as homologous pairs during the first stage of meiosis, known as prophase I.

How many times do spindle fibers form during meiosis?
Spindle fibers form twice during meiosis: once during meiosis I to separate homologous chromosomes and once during meiosis II to separate sister chromatids.
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
