The formation of multivalents at meiosis in diploid organism is due to
1 monosomy
2 inversion
3 deletion
4 reciprocal translocation
Explanation:
D The formation of multivalents at meiosis in diploid organism caused by the reciprocal translocation. Monosomy - Monosomy takes place when a missing number of a chromosome. Instead of 46-chromosome, the person has only 45-chromosomes. It occurs in a syndrome known as turner syndrome. Deletion - It is a type of mutation that involves the loss of one or more nucleotide from a segment of DNA.

Meiosis occurs in:
1 somatic cells only
2 germ cells only
3 both (a) and (b)
4 none of the above
Explanation:
B Meiosis occurs in germ cells only. Somatic cells are the cells that make up the body of an organism. germ cells that give rise to gametes. Meiosis is the process that produces gametes from germ cells.

Pairing of homologous chromosomes takes place during
1 leptotene
2 zygotene
3 pachytene
4 diplotene
Explanation:
B Pairing of homologous chromosomes takes place during zygotene, where the homologous chromosomes comes into close contact and align themselves along their length. This process called synapsis. Once synapsis completed the homologous chromosomes are held together by protein called synaptonemal complex.

Meiosis can be observed in :
1 tapetal cells
2 megaspores
3 micropores
4 microspore mother cells
Explanation:
D Meiosis is that type of cell division which reduces the number chromosome in gametes. The process of meiosis best seen in microspore mother cell which formed by the division of various stages in sporogenous tissue.
