How does the anaphase stage differ in the two phases of meiosis?
Ronch [10]

The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.


Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II. 

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.

 In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.

46 chromosomes

Explanation:

In mitosis (I think it is this process) the 46 chromosomes in cell A replicate themselves, so there are 92 in total in cell B. Then the chromosomes are pulled apart and the cell splits into 2 daughter cells, leaving 46 chromosomes in each.
