sattari [20]

Answer:

c. Either anaphase I or II of meiosis

Explanation:

During anaphase I homologous chromosomes separate, and they end up at opposite poles of the cell each having 2 chromatids, thus producing two daughter cells each with half the original chromosome number.

The two daughter cells resulting from meiosis I enter meiosis II, and during anaphase II the chromatids separate to opposite poles of the cells, producing a total of four daughter cells with half the original chromosome number and only one chromatid per chromosome.

  • If something goes wrong during <u>anaphase I</u> one pair of the homologous chromosomes will migrate together to one pole of the cell, and after going through meiosis II there will be 4 daughter cells, two of them having an extra chromosome and two of them lacking one.

  • If something goes wrong during <u>anaphase II</u>, the homologous chromosomes have separated but the chromatids of one of the chromosomes will migrate together, producing a total of 4 daughter cells: 2 normal, one with an extra chromosome and one lacking a chromosome.
