Differences between meiosis I and meiosis II include:
a
the pairing of chromosomes in meiosis I but not meiosis II.
b
the amount of DNA in a cell at the end of meiosis I or meiosis II.
c
how the chromosomes line up at the equator of the cell during meiosis I or meiosis II.
d
all of these are correct
d) all of these are correct.
Meiosis I involves the pairing of homologous chromosomes and crossing over, which does not occur in meiosis II. At the end of meiosis I, the resulting cells have half the amount of DNA as the original cell, while at the end of meiosis II, the amount of DNA remains the same. Additionally, during meiosis I, chromosomes line up in pairs at the equator of the cell, while during meiosis II, the sister chromatids line up individually.
