Answer
At anaphase II, each cell has 3 chromosomes.
Solution
To determine the number of chromosomes present in a cell during anaphase II of meiosis, we need to understand the process of meiosis:
-
Meiosis Overview: Meiosis consists of two rounds of cell division: meiosis I and meiosis II.
- In meiosis I, homologous chromosomes are separated, resulting in two cells, each with half the number of chromosomes (haploid).
- In meiosis II, the sister chromatids of each chromosome are separated.
-
Starting Condition: The parent cell starts with 6 chromosomes. This means it has 3 pairs of homologous chromosomes.
-
After Meiosis I:
- The cell divides into two haploid cells, each with 3 chromosomes (since homologous pairs are separated).
-
After Meiosis II:
- Each of the two haploid cells divides again, separating the sister chromatids.
- Therefore, each of the two cells will produce two cells, resulting in a total of four cells.
At anaphase II, each of the four cells will have the same number of chromosomes as the haploid cells from meiosis I, which is 3 chromosomes.
Thus, the answer is 3 chromosomes will be found in the cell at anaphase II.

During meiosis, the parent cell undergoes two divisions: meiosis I and meiosis II. By the time it reaches anaphase II, each of the two daughter cells produced from meiosis I will have half the original number of chromosomes. Starting with 6 chromosomes, during meiosis I, they are reduced to 3 chromosomes each. Therefore, during anaphase II, where the sister chromatids are pulled apart, the total number of chromosomes will still be 3.
So the answer is 3.
In a fun twist, think of it like dividing your candy stash for a movie night! You start with 6 candies (chromosomes), share half with a friend during the first movie (meiosis I), and finally, you each end up with 3 candies by the second movie’s climax (anaphase II). Who doesn’t love a good candy-sharing story? 🍭
