Evolution

6. Why Sex? Robert Vrijenhoek, from Monterey Bay Aquarium Research Institute, and his students were on a mission to find out why antheral topminnows were needed if the female topminnows bay window sick agamously by making identical copies of themselves and also to find out why is sex needed. Robert Vrijenhoek and his students conducted a test in one of Mexicos ponds where they found topminnows that were touched by a parasite that causes calamitous spot disease. According to the video Why Sex? the idea concluded that although both sexual and agamogenetic reproducing minnows god in the kindred pond the asexual minnows appeared to be parasitized more than the sexual reproducing minnows. afterwards analyzing the asexual minnows in detail they quickly realized that the asexual minnows had stopped evolving because they were exact copies of their mothers; their genetic information was the same it did non gain or adapt to the parasites that were in the pond divergence t hem to be easily bear upon by the parasitic disease. growing is a race, it does not stop, therefore we have to detect evolving in run to stay in the same place and later on necessitateing the sexual minnows they realized that sex generates gene variation importation that sex is important in order to keep a race alive and evolving which is why the asexual minnows were abnormal such(prenominal) more easily than the sexual minnows. In ratiocination Robert and his students ascertained that the reason for male minnows and sex is so that they can reproduce new combinations of genes so that their race can live to live in the same environment. According to the article create verbally by Curtis, Craddock, and Vrijenhoek the Red Queen guesswork prediction for the field of operation was that the more common clone would be the population that would be much more infected than the coexisting sexual populations. This opening means that the asexual reproducing organisms will be th e most affected by the infectious black spot! disease because since they on the whole replicate...If you want to get a full essay, order it on our website: OrderEssay.net
