Crossing over is an exchange of genetic material between
1 Sister chromatids of homologous chromosome
2 Non-sister chromatids of homologous chromosome
3 Non-homologous chromosome
4 Sister chromatids of non-homologous chromosome
Explanation:
Crossing over is an exchange of genetic material between non-sister chromatids of homologous chromosome. It occurs during Pachytene stage of Prophase – I.

During meiosis I, the chromosome starts pairing at
1 Zygotene
2 Pachytene
3 Diplotene
4 Leptotene
Explanation:

The stage during which separation of the paired homologous chromosomes begins is
1 Diakinesis
2 Diplotene
3 Pachytene
4 Zygotene
Explanation:
In diplotene stage of meiosis I, dissolution of synaptonemal complex takes place, Recombined homologous chromosomes separate from each other except at regions of cross over.

Recombination nodule formation is a characteristic of which of the following phases?
1 Zygotene
2 Diplotene
3 Leptotene
4 Pachytene
Explanation:
Pachytene is characterised by the appearance of recombination nodules, the sites at which crossing over occurs between non-sister chromatids of the homologous chromosomes.
