During meiosis ii select one: a. chromosomes undergo reductional division b. bivalents are formed during prophase ii and are taken apart during anaphase ii c. all of these choices are correct d. non-sister chromatids exchange maternal and paternal dna e. sister chromatids are separated

E. sister chromatids are separated.

Explanation:

Meiosis I is the reduction division as homologous chromosomes move to the opposite poles of the cell during anaphase II. Meiosis I does not include synapsis of homologous chromosomes and crossing over. These events are exclusive to the meiosis I.

Meiosis II includes alignment of chromosomes on the equator of the cell during metaphase II. Each chromosome has two sister chromatids. Splitting of centromere leads to the separation of sister chromatids during anaphase II. These separated sister chromatids move to the opposite poles of the cell. Formation of nuclear envelop around the two sets of sister chromatids present at the opposite poles of the cell marks telophase II.

uh two lol
