Witryna27 lut 2024 · Chiasmata is the point where two homologous non-sister chromatid exchange genetic material during a process known as crossing over. Crossing over is the first source of variation during meiosis. The homologous chromosomes are non-identical as they may have different alleles because their origin is from different … WitrynaMeiosis generates genetic variation in the diploid cell, in part by the exchange of genetic information between the pairs of chromosomes after they align (recombination). Thus, on this view, an advantage of meiosis is that it facilitates the generation of genomic diversity among progeny, allowing adaptation to adverse changes in the … Witryna3 lut 2024 · Introduction.
