In most cases, the chromosomes line up properly and crossover (left panel). The unequal crossover (right panel) occurs because of "selfish DNA" sequences known as transposons, represented here as ...

Unlike somatic cell division, which duplicates and divides the genome identically, meiosis creates genetically diverse reproductive cells through a mechanism known as crossover. Meiosis and ...

Understanding the steps of meiosis is essential to learning how errors occur. Researchers' initial understanding of meiosis was based upon careful observations of chromosome behavior using light ...

Unlike somatic cell division, which duplicates and divides the genome identically, meiosis creates genetically diverse reproductive cells through a mechanism known as crossover. Meiosis and ...

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two ...
