Crossing over takes place on -a)Two stranded stageb)Three stranded sta...
As crossing over occurs between Non-sister chromatids of Homologous Chromosome (H.C.) &1 H.C. consist of 2 chromatids and there are two H.C. i.e. 4 chromatids are present. Usually crossing over involves only 2 of the 4 chromatids of two H.C. however double or triple crossing over may involve all 4 ,3 or 2 chromatids which is very rare. But universally it is accepted that crossing over take place at 4 strands state..

Crossing over takes place on -a)Two stranded stageb)Three stranded sta...
Explanation:
The process of crossing over, also known as recombination, occurs during meiosis, specifically during prophase I. This process involves the exchange of genetic material between homologous chromosomes, resulting in genetic variation in offspring.
Key Points:
- Crossing over takes place during meiosis.
- It occurs at the four stranded stage, also known as the tetrad stage.
- The tetrad stage refers to the alignment of homologous chromosomes, which consists of two pairs of sister chromatids.
- During crossing over, sections of genetic material are exchanged between non-sister chromatids of homologous chromosomes.
- This exchange of genetic material leads to the formation of new combinations of genes.
- Crossing over promotes genetic diversity and increases the chances of offspring survival in changing environments.
Conclusion:
To summarize, crossing over takes place during meiosis at the four stranded stage, where sections of genetic material are exchanged between homologous chromosomes. This process promotes genetic diversity and contributes to the survival and adaptation of offspring.
