Cynthia observed a cell with a pair of sister chromatids moving toward a given pole as a single unit and another cell with sister chromatids moving to opposite poles. what did she infer from
her observation?
a) the first cell is in anaphase l, and the second cell is in anaphase ll
b) the first cell is in metaphase ll, and the second cell is in metaphase l
c) the first cell is in anaphase ll, and the second cell is in anaphase l

Meiosis is a process in which reduction of chromosomes take place
as a result of meiosis I two haploid cells form and 4 form as a result of meiosis II ad there are two anaphase in meiosis I and II 
so te correct option is A that is
the first cell is in anaphase l, and the second cell is in anaphase ll

and a pair of sister chromatids moving toward a given pole as a single unit and another cell with sister chromatids moving toopposite poles.because rthey have same polarity and they repel each other
hope it helps
