question 32
how do two sister chromatids entering meiosis ii differ?
o they are homologous pairs now
they are half their original size
they are not identical to each other
they are identical

Explanation:

During meiosis I, crossing - over occurs between homologous chromosomes. This leads to genetic recombination. Sister chromatids that enter meiosis II are the result of DNA replication (which makes them initially identical in a non - crossing - over scenario) but crossing - over in meiosis I disrupts this identity. So, sister chromatids entering meiosis II are not identical to each other due to genetic recombination events (crossing - over) that occurred in meiosis I.

Answer:

they are not identical to each other
