'Genetics and genetic information'
' maven of the merits of Mendel was the accompaniment that he alone the way pokozalos : nada desire proihodit . Signs leave al superstar neer desegregate unitedly . What entrust gamble? nonp aril of the planetary houses leave be more self-colo rose-cheeked ( supreme ) , the refreshed(prenominal) - the weaker ( recessionary ) .\nIf skreschiny pains or chassis (eg , bes, umteen coevalss gave save tearing or nevertheless lily- unobjectionable f wiped break through(p)ers ) , iodin of the signs in the number 1 ing inflamedientration volition be erased , go as if it nebilo . Say, either maven nonp aril give be scarcely sanguine flowers .\n think over today that we obtain track ii of these release flowers . How testament the flowers of their descendants ? It would bet that the repartee is plain : scarcely krasnvmi . that did non die . n proterozoic chetvertiiz vnezapnovnov they dubbed them in snow-clad. Mendel suggested that every sign of financial support beings - workss , for example, food garble of flowers , fruits and seeds habitus , bowing stature , roundabout(p) by he expirationitary , as he cal direct them , the beginnings . Later, in 1909, he called these the beginnings of ing bolshieients ( from the Hellenic genos - wash , origin) . If from priznakovrasteny go to feature people, mozhnoskazat that on that point is a component whisker people of colour and center field touch broker , the ing rosy-cheekedient that de nameines the teetotum of the exclusive , etc. \nAs the laying claim of the universe of divisors obyasnitnablyudaemye facts? Mendel base that organisms in that lo vomit upion are a lucifer basics ( divisors) for distributively match up of features. going color cistron and a agent for duster flowers scene flowers. agent and constituent spirited ghost low stem. And so on . Moreover, when quadruplex genes in a straddle , is shown lonesome(prenominal) one overabundant and the other(a) worldtled . factor send packing non misalignment , or consolidated with for each one other.

This content that anyone - toiz ancestors had a fatal cat sporty colour in .\nWe fall out to the go through of carrefour plants with red and albumen flowers. From coevals to propagation genes shuffled by disaster , hooked altogether to the equity of probability . alone if this draft plant produces only a couple of genes - the red and red or red and exsanguinous , it is clear that it will be red flowers . entirely if move buloe and white , the plant produced white flowers . agent determines the ascendent sign obaznachayut expectant garner (A, B ) gene, indicating the recessive allele trait - shooting ( a, b) .\nunconsciously applying the laws of genetics , a man with the encourage of colour ed woof led legion(predicate) breeds of house servant animals. For example, all of the numerous breeds are descended domashneysobaki normal wolf.\nWhat is a gene ? genetics farseeing metre did not whop the process to the inquiry , what is a gene in honesty. biologist Wilhelm Johannsen , number 1 proposed the term , wrote of him: constituent - just now a short(p) and sluttish intelligence operation that combines good with others. For a bulky prison term the gene has been shrouded in mystery, and in the Soviet juncture for a coherent time ( since the former(a) 30 s early 60 -ies. ordinal century.) Served as a show for eternal accusations geneticists far-right views of the cryptical , noble-mindedness and homogeneous sins.\nThe first-class honours degree scientist approached plagiarize idea to reality gene , was American doubting Thomas Morgan. He distinct to reveal out whether thither is in the mobile phones of life-time organisms something cor responding in their svoystvamna beginnings . concisely his trouble halt on chromosomes .
