Question

What happens at the recombination nodules in the pachytene phase?

Answer 1

Recombination Nodule:

1. These are the sites where crossing over takes place between non-sister chromatids of the homologous chromosomes.
2. Prophase-I of meiosis-I is the unique phase that involves the recombination of genetic material between homologous chromosomes.
3. This occurs in the pachytene stage where non-sister chromatids of the homologous chromosomes cross over & exchange of genetic material takes place.
4. Recombination nodules are place at which the non-sister chromatids crossover.
