The appearance of recombination nodules on homologous chromosomes during meiosis characterizes:
1 Bivalent
2 Sites at which crossing over occurs
3 Terminalization
4 Synaptonemal complex
Explanation:
The appearance of recombination nodules is the sites at which crossing over occurs between non-sister chromatids of the homologous chromosomes during meiosis-I.

Meiosis in plants occurs in
1 Root apex
2 Ovules
3 Anther
4 2 and 3
Explanation:
In plants, meiosis takes place in anther to form pollen (n) and ovules too form egg (n).

During anaphase-I of meiosis
1 Homologous chromosomes separate
2 Non-homologous autosomes separate
3 Sister chromatids separate
4 Non-sister chromatids separate
Explanation:
Homologous chromosomes separate during Anaphase I.

In which stage of meiosis- I, the chromosome is thin, long and thread-like?
1 Pachytene
2 Zygotene
3 Leptotene
4 Diakinesis
Explanation:
Leptotene is the beginning of prophase where chromosomes appear as thin, long threads. Condensation and coiling of chromatin fibres begins in this stage.
