Meiosis includes two rounds of the five steps of mitosis, but with many twists to ensure that the sperm or egg cell created is genetically different from either parent. This is caused bycrossing over(the exchange of bits of DNA between homologous chromosomes) andindependent assortment(the random ...
Do eggs and sperm arise by mitosis or meiosis? Mitosis happens when you want to grow, for example. You want all your new cells to have the same DNA as the previous cells. The goal ofmeiosis, however, is to produce sperm or eggs, also known as gametes. Are gametes formed through mitosis?

Scientists will not be able to fully understand Quantum Mechanics, vision, consciousness, autism, savant abilities, nor cellular control, including DNA replication, mitosis, meiosis, and certainly not cancer, nor will they solve the Binding Problem until scientists look...
In contrast, oocytes in the female arrested at the prophase of meiosis I remain hypomethylated throughout the fetal period [63,64,65]. DNA methylation will only be acquired by the same enzymatic machinery as that in male germ cells [66, 67] in the post-pubertal period during each cycle ...
