  Gregor Johann Mendel

  Gregor Johann Mendel was an Austrian scientist who gained posthumous fame as the founder of the new science of genetics. Mendel demonstrated that the inheritance of certain traits in pea plants follows particular patterns, now referred as the laws of Mendelian inheritance.

  The most important reasons for Gregor Johann Mendel’s epochmaking contributions to the discipline of genetics lay in his passion for the subject, and his scientific and serious attitude towards research. For eight years, he carefully bred 22 kinds of peas that he deliberately chose for experiments. Usually when guests came to visit the peas, he would proudly boast: “These are my sons and daughters.” And in the eight years, he continuously conducted experiments, having precise observation, careful calculation and detailed analysis to characteristics and numbers of peas of different sorts and generations.

  What’s more, even when he himself knew that his research finding about genetics would be a landmark in the field of science, he repeated the experiments cautiously for some years to

  make it more logical and perfect before publicizing it, and also did plenty of similar studies on other plants like corns, violets and Mirabilis jalapa, by which he tried to verify the applicability of the laws of genetics on most of plants.

  乔治·约翰·孟德尔

  乔治·约翰·孟德尔是位奥地利科学家,死后出名,但他的贡献使他被赞誉为现代遗传学之父。孟德尔发现豌豆某些特性的遗传是遵行特定的形式的,也就是现在所说的孟德尔遗传定律。

  乔治·约翰·孟德尔之所以能够在遗传学领域做出划时代的贡献,最重要的原因是他对这门科学的热爱以及对研究的科学严谨的态度。

  八年来,他仔细挑选并培育了22种豌豆以供实验之用。每当有客人前来参观豌豆时,他总是骄傲地说:“这些都是我的儿女!”在这八年期间,他也不断地做豌豆实验,对不同种类和不同代的豌豆的性状和数目进行细致入微的观察、计数和分析。

  除此之外,即使当他明白他的关于遗传学的研究发现在科学史上具有里程碑意义时,他在公开之前,仍旧慎重地重复实验了多年,以使它更加完善;同时他也对其他植物作了大量的类似研究,其中包括玉米、紫罗兰和紫茉莉等,以期证明他发现的遗传规律对大多数植物都是适用的。

  以上就是关于SAT写作经典例子之Gregor Johann Mendel的相关介绍,大家在遇到大众观点类、选择类、成功类等话题的时候,可以适当的更加详细的了解详细内容并选择合适的角度切入使用。大家可以在备考自己的SAT写作考试的时候根据自己的实际情况进行适当的应用
