How meiosis generates variation

WebIn most organisms, meiosis produces haploid gametes from diploid precursor cells. Meiosis halves the chromosome number via two successive rounds of chromosome segregation that follow a single round of chromosome replication. WebAnalyzing genetic variation Aminur Fahim 02/13/ Marquez Shelly OIAHS. Analyze claims. i. Inherited genetic variations are caused by genetics only. They are caused by crossing over and assortment in the development of sex cells in meiosis. The random joining of sex cells can also be a source of genetic variation.
