Genetic content of a cell reduces to half during
1 meiotic prophase I
2 mitotic prophase
3 meiotic prophase II
4 meiotic telophase
Explanation:
D Meiosis is a specialized from of cell division in which number of chromosomes is reduced to half, creating genetically distinct haploid cells. Telophase I - The meiosis-I effectively ends when the chromosomes arrives at the poles. Each daughter cell now has half the number of chromosomes but each chromosomes consist of a pair of chromatids.

During meiosis there is
1 one round of DNA replication and one divisions
2 two rounds of DNA replication and one divisions
3 two rounds of DNA replication and two divisions
4 one round of DNA replication and two divisions
Explanation:
D Meiosis is a type of cell division that produces four haploid cells from a single diploid cell. It involves one round of DNA replication followed by two rounds of cell division. The first round of cell division is called meiosis \(\mathrm{I}\), and the second round is called meiosis II.

Crossing over occurs
1 single strand stage
2 two strand stage
3 four strand stage
4 eight strand stage
Explanation:
:In diplotene stage of prophase I of meiosis, each chromosome splits longitudinally into two chromatids and now bivalent is composed of four chromatids. This state is known as the four -strand stage or tetrad. Crossing over occurs in 4-strand stage It refers to the exchange of genetic material or chromosome segments between non- sister chromatids in meiosis. Crossing over is an enzyme mediated process, where the exchanges of genetic material between non-sister chromatids of homologous chromosomes takes place, its occur at the pachytene stage of prophase-I of meiosis.

When synapsis is complete all along the chromosome, the cell is said to have entered a stage called?
1 zygotene
2 pachytene
3 diplotene
4 diakinesis
Explanation:
B Synapsis is the process of pairing of homologous chromosomes. It occurs during the pachytene stage of prophase I of meiosis. When synapsis is complete all along the chromosome.. The cell is said to have entered the pachytene.

Synaptonemal complex is a structure of
1 cytokinesis
2 terminalisation
3 chromosomal disfunction
4 chromosomal pairing
Explanation:
D The synaptonemal complex is a protein structure that forms between homologus two pairs of sister chromatids, during meiosis. It is a protein lattice that resembles railroad tracks and connects paired homologous chromosomes in most meiotic systems. It is thought to mediate synapsis and recombination during meiosis-I in eukaryotes. It is a complex protein structures.
