Web10 jun. 2024 · Crossing Over may be defined as the exchange of a part of a chromatid from one homologous chromosome with an equivalent part of a chromatid from the other homologous chromosome. This exchange results in a new gene combination. Remember that a chromosome is a double strand of DNA. Webmeiosis and chromosome role. Each pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids. At this point, the homologous chromosomes exchange genetic material by the process of crossing over ( see linkage group). The homologous pairs line up along the midline of the cell in metaphase I and then separate in anaphase … Web1. Single cross over: When only one chiasma occur only at one point of the chromosome pair. It produces two non-crossover chromatids and two crossover chromatids. 2. Double cross over: when crossing over occurs at two points between any two given points in the same chromosome pair, it is called double crossing over. It produces FOUR crossovers. can allopurinol be crushed
