During anaphase-I of meiosis (a) Homologous chromosomes separate (c) Sister chromatids separate(b) Non-Homologous autonomous separate (d) Non-Sister chromatids separate |
|
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'.Explanation:hope this will help you |
