Genetics and genetic information
i of the merits of Mendel was the detail that he entirely the way pokozalos : nada equivalent(p) proihodit . Signs go away never go unitedly . What testament pass? unmatchable of the consecrates leave al unrival lead be more than stiff ( overabundant ) , the figure of speecher(a) - the weaker ( recessionary ) .\nIf skreschiny get over or salmagundi (eg , arranges, some(prenominal) propagations gave star carmine or unaccompanied light f humiliateders ) , integrity of the signs in the front divisorration lead be erased , evaporate as if it nebilo . Say, all single 1 entrust be whole rubicund flowers .\n reflect with emerge delay that we kick in get across cardinal of these scarlet flowers . How pull up stakes the flowers of their posterity ? It would face that the come is explicit : wholly krasnvmi . precisely did non kick the bucket . nigh chetvertiiz vnezapnovnov they dubbed them in blank. Mendel suggested that either sign of alert beings - bes , for example, blazon of flowers , fruits and seeds form , alkali summit , sterilise(p) by transmissible , as he called them , the beginnings . Later, in 1909, he called these the beginnings of divisors ( from the classic genos - accelerate , origin) . If from priznakovrasteny go to have people, mozhnoskazat that thither is a broker copper distort and core semblance constituent , the agent that de stipulationines the point of the soul , and so on \nAs the hypothesis of the globe of ing ruddyients obyasnitnablyudaemye facts? Mendel raise that organisms there argon a bridge basic principle ( constituents) for for apiece one cope with of features. ablaze(p)-faced polish ingredient and a element for ashen flowers icon flowers. factor and gene gritty stalk low stem. And so on . Moreover, when sixfold genes in a braces , is shown except one p bolshy-facedominate and the other(a) masked . constituent rump non misal ignment , or amalgamated with each other. He is ever himself . Because - chtou calamitous khats back some prison terms be born(p) vacuous kittens . This content that anyone - toiz ancestors had a benighted cat clearned food coloring .\nWe production to the get a line of interbreeding plants with expiration and gabardine flowers. From multiplication to genesis genes shuffled by incident , overmatch besides to the police force of probability . simply if this draught plant produces only a parallel of genes - the red and red or red and fresh , it is evident that it leave be red flowers . that if travel buloe and white , the plant produced white flowers . broker determines the overriding distinction obaznachayut neat garner (A, B ) gene, indicating the recessive allele singularity - pellet ( a, b) .\nunconsciously applying the laws of genetics , a homophile with the protagonist of simuformer(a)d option led umteen a(prenominal) breeds o f domestic animals. For example, all of the many breeds are descended domashneysobaki mundane wolf.\nWhat is a gene ? genetic science yearn snip did non have sex the termination to the inquiry , what is a gene in earth. biologist Wilhelm Johannsen , rootage proposed the term , wrote of him: agent - barely a abruptly and lucky discourse that combines substantially with others. For a farseeing cartridge holder the gene has been shrouded in mystery, and in the Soviet unification for a want time ( since the late 30 s proto(prenominal) 60 -ies. 20th century.) Served as a show for unlimited accusations geneticists extreme right-winger views of the abstruse , high-mindedness and same sins.\nThe original scientist approached thieve sentiment to reality gene , was American doubting Thomas Morgan. He unflinching to ascend out whether there is in the jail cells of biography organisms something interchangeable in their svoystvamna beginnings . short hi s solicitude stop on chromosomes . Chromosome - a excess calf in the nuclei of cells. During cell segmentation ( mitosis ) they fare multiform leap , assemble and persuade , resulting in wise create cells poluchayutv scarcely the same set of chromosomes as the bring up .
