Crossing-over is the interchange from bits ranging from non-sister chromatids of homologus chromosomes during meiotic prophase (pachytene). Put simply, crossing-over results from change out-of hereditary question between non-brother chromatids involving damage and reunion on perfect area. The phrase crossing-over was initially used by Morgan and you can Cattell when you look at the 1912.
step one. Crossing over happens during meiotic prophase, we.elizabeth., during the pachytene. For each and every pair of chromosome keeps four chromatids at that time.
2. Crossing over happens ranging from low-sis chromatids. Hence you to definitely chromatid off each of the several homologus chromosomes was working in crossing-over. Read More
