Question

with the help of suitabal diagrams explain the stages of prophase I of meiosis​

Answer 1

Answer:

Meiosis is a cell division which takes place in germ cells during sexual reproduction. It is completed in stages Meiosis- I and Meiosis-II.

5 phases of prophase –I of meiosis given below:

1: The duplicated sister chromatids start to condense.

2. The homologous chromosomes (pair of chromosome having same set of genes) come close to each other and begins to form a paired homologous chromosome. Four chromatids, with one chromosome coming from each parent. Each pair of homologous chromosomes is known as a bivalent (Tetrad).

3. The paired chromosomes are held together tightly. Crossing over (exchange of chromosome segment between non-sister chromatids) between homologous chromosomes occurs. This results into genetic recombination.

4. The homologous chromosomes begin to separate.

5. The chromosomes continue to condense further and the nuclear membrane breaks.
