Question

all but one event would occur during meiosis i. that is
a homologous chromosomes pair up.
b sister chromatids divide, resulting in haploid cells.
c nuclear membrane form around newly separated chromosomes.
d homologous chromosomes are separated with sister chromatids in place.

Explanation:

During Meiosis I, homologous chromosomes pair up (synapsis), homologous chromosomes are separated while sister - chromatids remain attached, and a nuclear membrane can form around newly separated chromosomes. Sister chromatids divide to result in haploid cells during Meiosis II, not Meiosis I.

Answer:

B. sister chromatids divide, resulting in haploid cells.
