孟德尔的介绍,英文的...急需

A monk with a scientific streak, Mendel made botanical discoveries which became the basis of modern genetics. His careful cross-breeding of thousands of pea plants led Mendel to key insights, now called Mendel's Laws of Heredity, about how inherited traits are passed on from generation to generation. As a young man Mendel entered the St. Thomas Monastery in Brünn, Austria (now Brno, the Czech Republic). He devoted much of his time to teaching and scientific inquiry. Between 1856 and 1863 he catalogued successive generations of pea plants with statistical precision, looking for clues to how traits like color and shape were reproduced. Among his findings were the law of segregation (which includes the notion of dominant and recessive genes) and the law of independent assortment (which says that an organism's individual traits are passed on independently of one another). Mendel published Experiments in Plant Hybridization in 1865, but his theories were not widely embraced until the 1900s.Mendel was made abbot of the St. Thomas Monastery in 1868... His birthplace of Hyncice is also known by its former German name, Heinzendorf.

基因学说的创立者是孟德尔还是摩尔根

遗传因子(hereditary factor)的概念,最初是由孟德尔提出的。他的三大遗传规律奠定了遗传学的基础。但在当时历史条件下,他的科学发现和见解,没有引起生物学界的同行的注意。湮没了35年之后,即1900年才被荷兰的H.De Vries 、德国的C.Correns和奥地利 E.Tschermak等植物学家重新发现。

1909年,丹麦生物学家W.Johannsen根据希弊稿腊文“给予生命”消卜凯之义,创造了基因(gene)一词,并用这个术语代替孟德尔的“遗传因子”。不过他所说的基因并不代表物质实体,而是一种与细胞的任何拿唤可见形态结构毫无关系的抽象单位。因此,那时所指的基因只是遗传性状的符号,还没有具体涉及基因的物质概念。

美国著名的遗传学家摩尔根(T.H.Morgan)对基因学说的建立作出了卓越的贡献。他和他的助手以果蝇作为实验材料,第一次将代表某一特定性状的基因,同某一特定的染色体联系了起来,创立了遗传的染色体理论。随后遗传学家又应用当时发展的基因作图(gene mapping)技术,构筑了基因的连锁图,进一步揭示了在染色体载体上基因是按线性顺序排列的。
