the phenomena of exchange of genetic material between the non sister chromatids but between the homeo logos known as crossing over and it occurs during prophase stage which is further divided into leptotene zygotene pachytene diplotene and diakinesis in prophase crossing over mainly occurs in the pachytene stage and recombination nodules are formed at the site of crossing over between non sister chromatids of homologos chromosomes crossing over is also in enzyme mediated process and the enzyme involved is called recombinase

CROSSING OVER is “exchange of genetic material between non-sister chromatids” occurs during in this division.

Explanation:

  • Chromosomal cross over is the transfer of hereditary “material between two homologous chromosomes non-sister chromatids” that outcome in recombinant chromosomes during sexual multiplication.
  • It is one of the last periods of hereditary recombination, which happens in the pachytene phase of prophase I of meiosis during a procedure called synapsis.  
  • Synapsis starts before the synaptonemal complex creates and isn't finished until close to the finish of prophase I.
  • Hybrid as a rule happens when coordinating areas on coordinating chromosomes break and after that reconnect to the next chromosome.
