Non disjunction in meiosis is the failure of homologous chromosome or sister chromatids to separate properly during meiosis. This can result in the production of gametes with an abnormal number of chromosomes, such as trisomy(having three copy of chromosome instead of the usual two)

In biogas plant, the role of acidogenic bacteria is to
1 Convert monomers to organic acids
2 Convert monomers to complex polymers
3 Transform acetic acid to biogas
4 Digest fungi in the sludge
Explanation:
A Acidogenic bacteria breakdown complex organic matter into monomers, These organic acids are then used by bacteria in the biogas plant to produce methane, which is the main component of biogas.

The stage during which separation of the paired homologous chromosomes begins is
1 Pachytene
2 Diplotene
3 Zygotene
4 Diakinesis
Explanation:
B During diplotene the homologous chromosome develops a repulsive force and begins to separate from each other. Terminalization begins at diplotene stage i.e. chiasmata start to shift towards end. The separation of homologous chromosome and dissolution of synaptonemal complex occur at diplotene stage.In zygotene phase function of synapsis occur. During the pachytene crossing over between non-sister chromatid of homologous chromosome. Diakinesis marked by terminalization or chiasmata. Phase of meosis : Leptotene \(\rightarrow\) Zygotene \(\rightarrow\) Pachytene \(\rightarrow\) Diplotene \(\rightarrow\) Diakinesis

Synapsis is characteristic feature of
1 Leptotene
2 Zygotene
3 pachytene
4 Diplotene
Explanation:
B It is a characteristic features seen in the process of meiosis during formation of male and female gametes. The pairing of homologous chromosome during meiosis is referred to as synapsis. Synapsis is found in the zygotene stages of prophase-I in meiosis.

Formation of chiasmata is the characteristic feature of
1 diplotene
2 pachytene
3 zygotene
4 diakinesis
Explanation:
A Formation of chiasmata is occurs during the stage of deplotene of prophase-I. In this stage the crossing over is completed. Chiasmata is formed at the sites of crossover. These X-shaped structures are called chiasmata.
