Summary: Mendel\'s laws

abbreviation: Mendels laws\n\nMendelian supposition of heredity, ie unsex of representations of genetic determinants and on the nature of their transmission system from p bent to publication, in its meaning is on the nose the opposite domendelevskim theories, in crackicular the possibleness of pangenesis, Darwin proposed. In concurrence with this theory signs p atomic number 18nts directly, ie all split of the body atomic number 18 transmitted to offspring. Therefore, the contribution trait offspring should directly play on the properties of the p atomic number 18nt. This exclusively contradicts the findings of Mendel: determinants of heredity, ie genes are present in the body is comparatively independent of itself. percentage traits (phenotype) is determined by the random combination. They are not special with any part of the body and are in a relationship of dominance-recessive. Thus, the Mendelian theory of heredity opposed to the radical of ​​herita ge of acquired during case-by-case development features.\nMendels experiments were the fanny for the development of clean-made genetics - the intelligence that studies the two main(prenominal) properties of the body - heredity and variation. He was competent to identify patterns of inheritance due to a fundamentally overbold technical approaches:\n1), which is Mendel chose to convey;\n2) he conducted outline of the inheritance of individual traits in the progeny plants in crosses, differing by one, two or three duplicates of secernate alternative characters. In every extension was conducted separately bet for each pair of these traits;\n3) it is not near the results recorded, but held their numerical treatment.\nThese simple techniques the remove was fundamentally new method of poring over the inheritance Hybridological, which became the terra firma for further research in genetics.
