WebCrossing over is a concept of genetics that is often called recombination. It occurs during meiosis. Crossing over is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes during the production of gametes. So the correct option is "Two non-sister chromatids of homologous chromosomes". WebCrossing over definition, the interchange of corresponding chromatid segments of homologous chromosomes with their linked genes.

The chiasma (plural: chiasmata) is the connecting point between two non-sister chromatids which allows for the exchange of alleles. Chiasmata can only form if the sister chromatids are separated from … WebJun 7, 2024 · Answer: C. homologous chromosomes. Explanation: Crossing over occurs between prophase I and metaphase I and is the process where two homologous non-sister chromatids pair up with each other and exchange different segments of genetic material to form two recombinant chromosome sister chromatids. andros fruit me up coop WebOct 27, 2024 · In prophase II, no crossing over occurs as this must take place between homologous chromosome pairs. The spindle apparatus forms in order to break apart the replicated chromatids. In a female, this results in secondary polar bodies, each containing a single chromatid (it can just as easily be called a chromosome) which itself contains the ... WebDec 9, 2024 · A crossing over between linked genes allows their recombination during meiosis. Crossing over takes place in pachytene stage of prophase I of meiosis. In pachytene stage, the bivalent chromosome becomes tetrad i.e. with four chromatids.
