Question

during anaphase-1 of moises​

Answer 1

Answer:

During anaphase I, from each tetrad, two chromatids of a chromosome move as a unit (dyad) to one pole of a spindle, and the remaining two chromatids of its homologus migrate to the opposite pole. Thus, the homologous chromosomes of each pair, rather than the chromatids of a chromosome, are separated. As a result, half of the chromosomes, which appear in early prophase, go to each pole. It is here in the anaphase I that the real reduction in the number of chromosomes occurs.

So, the correct answer is 'Homologous chromosomes separate'.
