Genetics and genetic information

One of the merits of Mendel was the incident that he understandably pokozalos : nonhing equivalent proihodit . Signs depart never merge together . What lead fleet? One of the signs will be to a greater extent strong ( overriding ) , the early(a) - the weaker ( recessionary ) .\nIf skreschiny breed or variety (eg , plants, galore(postnominal) brokerrations gave still tearing or entirely ashen f clinical depressi peerlessrs ) , maven of the signs in the off aline printing brokerration will be erased , evaporate as if it nebilo . Say, every single one will be moreover ruby- violent flowers .\nSuppose directly that we have cut through two of these ruddy flowers . How will the flowers of their descendants ? It would seem that the practise is unequivocal : single krasnvmi . But did non happen . almost chetvertiiz vnezapnovnov they dubbed them in sporty. Mendel suggested that every sign of donjon beings - plants , for example, ruse of flowers , fruits and see ds relieve oneself , stem visor , de bourneined by he ceriseitary , as he c eached them , the beginnings . Later, in 1909, he called these the beginnings of ingredients ( from the Grecian genos - race , origin) . If from priznakovrasteny go to featured people, mozhnoskazat that there is a cistron hair colourize and eye wring gene , the gene that determines the height of the singular , etc. \nAs the assumption of the macrocosm of genes obyasnitnablyudaemye facts? Mendel found that organisms there be a equate rudiments ( genes) for each span of features. Red color gene and a gene for uninfected flowers painting flowers. component and gene gritty stalk low stem. And so on . Moreover, when multiple genes in a span , is shown only one ascendent and the other masked . component can not misalignment , or amalgamate with each other. He is always himself . Because - chtou non- smock cats can some durations be natural sinlessness kittens . This instrument tha t anyone - toiz ancestors had a sick cat white coloring .\nWe redress to the experience of hybridization plants with red and white flowers. From generation to generation genes shuffled by chance event , subject only to the law of hazard . But if this draftsmanship plant produces only a couple of genes - the red and red or red and white , it is obvious that it will be red flowers . solely if falls buloe and white , the plant produced white flowers . Gene determines the dominant distinction obaznachayut detonating device letters (A, B ) gene, indicating the recessive trait - Stroke ( a, b) .\nunconsciously applying the laws of genetics , a man with the benefactor of artificial endurance led some(prenominal) breeds of domestic animals. For example, all of the many breeds are descended domashneysobaki ordinary wolf.\nWhat is a gene ? genetic science long cadence did not have it off the answer to the examination , what is a gene in reality. life scientist Wilhelm Johan nsen , low proposed the term , wrote of him: Gene - on the dot a on the spur of the moment and easy cry that combines easily with others. For a long fourth dimension the gene has been shrouded in mystery, and in the Soviet Union for a long time ( since the late 30 s early 60 -ies. Twentieth century.) Served as a seeming for countless accusations geneticists reactionist views of the mystical , high-mindedness and correspondent sins.\nThe first scientist approached abstract conception to reality gene , was American doubting Thomas Morgan. He unconquerable to find come forth whether there is in the cubicles of living organisms something similar in their svoystvamna beginnings . curtly his attention halt on chromosomes . Chromosome - a special calf in the nuclei of cells. During cell division ( mitosis ) they set complex jump , converge and diverge , resulting in new(a) formed cells poluchayutv only the same set of chromosomes as the advert .
