How does gene flow cause natural selection? How are genes added to the gene pool? How are gene flow and genetic drift similar? Crossing over is one way that variation is increased in gametes. a. Give a definite of crossing over. b. Where does crossing over occur in meiosis and how does...
(a) What is crossing over? (b) How is meiosis related to this phenomenon?Meiosis:Meiosis is how gametes are produced during cell division. Gametes are sex cells, and reproduction cannot occur without them. There are various stages in a two-step process to meiosis: meiosis 1...

How does meiosis differs from normal cell division? 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. ... In contrast, meiosis gives rise tofour unique daughter cells, ea...
(2023) consider that most of the identified thermosensory genes in plants are related to thermomorphogenesis, and that heat perception and response are always interrelated and synergistic. This understanding has made some progress inArabidopsis. So how does rice perceive the increase in temperature and...
imposing constraints on Y fate. If small PAR size compromises XY segregation during male meiosis, the stress of producing aneuploid gametes could drive function away from the Y (i.e., a fragile Y). The Y chromosome can avoid fragility either by acquiring an achiasmatic meiotic XY pairing str...

When are sister chromatids formed - in mitosis or in meiosis? How does the process of crossing over create genetic variation? Why does meiosis result in a reduction of genetic material and why does meiosis result in genetic recombination?
Why does synapsis occur in meiosis and not mitosis? What are the unique processes in meiosis that are not present in mitosis? How is mitosis different in plants and animals? Which part of meiosis is the same as mitosis? Why does crossing over occur in meiosis but not in mit...
These are not easy to identify in humans, but one factor that has been shown to be of importance in fertility is the recombination rate at meiosis; reduction in crossing over is associated with an increase in aneuploid oocytes and lower fertility [27, 28]. Proteins that have been shown to...
