Question
By the end of this phase, the number of homologous chromosomes is reduced in half: a. Anaphase I b. Prophase II c. Metaphase II d. Prophase I
Correct Answer
Option A is the correct answer.
Detailed Explanation
The reduction in chromosome number (from diploid to haploid) occurs during anaphase I when homologous chromosomes separate and move to opposite poles. By the end of telophase I, each daughter cell has half the original number of chromosomes (though each chromosome still consists of two sister chromatids).
Hint
This is when the pairs are pulled apart.
