WebTopic - Cytological basis of Crossing Over, Paper - Genetics, Class - BSc (+3) Botany Honours, By M.R.Maharana WebThis is because, during the first meiotic prophase when homologous chromosomes undergo pairing, there is a reciprocal exchange of chromosome segments. This process is known as crossing-over. Crossing- over is responsible for the non-transmission of linked genes together and generation of recombinants.

By pachytene pairing is stabilized, and each ribbon-like chromosome actually consists of two homologues paired (synapsed) close to each other called bivalents. Each homologue in a bivalent consists … Webcytological crossing-over. It is the aim of the present paper to show that cytological crossing-over occurs and that it is accompanied by genetical crossing-over. Two cytological features were sufficient for the experiment: (i) a dark-staining, heterochromatic "knob" at the end of chromosome 9, and (ii) a reciprocal inter- grand game 2 tpir
