Do you have siblings? You may have similar traits, but you are also very different. We exhibit genetic variation, even in the sa
me family, thanks to sexual reproduction. During sexual reproduction gametes are produced through the process of meiosis. Gametes, egg or sperm, are haploid cells. The 46 chromosomes our body cells contain are reduced so when egg or sperm are produced, there are 23 chromosomes each. In any family, with the same parents, those 23 chromosomes vary every time a gamete is produced, except in the case of identical twins. Look at the diagram of meiosis. When the process is complete, each haploid gamete contains a variation of the original diploid cell. During meiosis chromosomes move randomly to separate poles. A human gamete will end up with 23 chromosomes after meiosis, but ________________ assures that each gamete will have one of many different combinations of chromosomes. A) law of dominance B) meiotic divisions C) reduction division D) independent assortment
Sports drinks contain water, sugar and mineral ions at levels which are most effective at maintaining performance as well as this it also replaces the glucose and maintaining the correct ion/water balance for cells to function effectively.
