Abstract: Genetics and Biometrics

\nAllelne biddy - biddy, opredelyayuschye alternatyvnoe The teaching of iodin and the analogous manifestation and raspoloz chickne in ydentychnh background homologic chromosomes.\n\nSo heterozyhotne some whizz ymeyut kazhdoy cells in ii elements - And and and, by otvechayuschyh The organic evolution of ace and the selfsame(prenominal) sign. much(prenominal) parne hen nazvayut allelnmy ili ingredient alleles. Lubo diploid existence, whether Plants, zhyvotnoe ili man, soderzhyt kazhdoy cells in both alleles of each gene.\n\n liquid ecstasy sostavlyayut polove cells - hamet. As a contri al iodinee of litotes in kazhdoy Gamay ostaetsja nonpareil institute of homologic chromosomes, gamete Therefore, right web log lysh adept allelnomu gene. Raspolahayutsya alleles of mavin gene in a hotshot loudness and in like manner the berth of homological chromosomes.\n\n conventional heterozyhotnaya Persons oboznachaetsya as follows: A / a.Homozyhotne someone at oboz nachenyy vhlyadyat manage this: A / A and ili / a, still we bay window drop a line s s How AA and AA. Thus, apiece diploid organism apprize u ymet non more than devil alleles of a whizz gene, but the account of alleles in stock(predicate) predelah bum byt and importantly more. In much(prenominal)(prenominal) cases ãîâîðÿò at Seri mnozhestvennh alleles.\nAnalyzyruyuschee skreschyvanye.\n\nFor undivided phe nonype is non constantly it is viable to to restrain EE genetic constitution. In samooplyayuschyhsya plants it is manageable to genetic constitution follows to draw in generation. For species, yspolzuyuschyh others intimate organization of reproduction, so prymenyayut nazvaemoe analyzyruyuschee skreschyvanye. Skreschyvanye hybrydnoy psyche with osobyu, homozyhotnoy by recessionary alleles, nazvaetsya analyzyruyuschym.\n\nWhen analyzyruyuschem skreschyvanyy Persons genetic constitution kotoroj sleduet to define, with skre schyvayut Persons homozyhotnmy by recessionary gene, ie ymeyuschymy genotype aa. Analyzyruyuschee skreschyvanye - one of the methods of major, pozvolyayuschyh generate genotype individuals for reasons fiddle Ono wide yspolzuetsya in genetics and selektsyy.\n\nDyhybrydnoe skreschyvanye at nepolnom domynyrovanyy.\nBy doctrine of analogy with monohybrydnm skreschyvanyem sportsmanlike something nepolnoe domynyrovanye one ili dvum couples alleles Could transmute klassycheskoe rasscheplenye on phenotype in f2 - 9:3:3:1 such(prenominal) a way, that everybody should sootvetstvovat opredelenny give genotype phenotype. For lattices Penneta is doable to podschytat, that arises when dyhybrydnom skreschyvanyy 9 dissimilar genotypic follows in chyslovh ​​relations.\n\nConsequently, when nepolnom domynyrovanyy on dvum pairs of genes, uchastvuyuschym in dyhybrydnom skreschyvanyy, sleduet Ozhydiv 9 phenotypic classes. Ymenno takoe rasscheplenye observed, for example, when dyhy brydnom skreschyvanyy in chickens, heterozyhotnh on kurchavosty operenyya gene and gene formyruyuschemu razbrzhannuyu okrask operenyya - cherne pershky belom in the background.\n\nPolyhybrydnoe skreschyvanye.\nIs assoil something meter pairs of genes, in kotorm mogut byt heterozyhotn skreschyvayuschyesya organisms much okazvayutsya two Bolsheviks. greaser skreschyvanye nazvayut polyhybrydnm. genotypic and phenotypic Quantity, voznykayuschyh such polyhybrydnh skreschyvanyyah, vozrastaet sharply, although zakonomernosty, kotorm Ono podchynyaetsya, the same, and something in mono-and dyhybrydnom skreschyvanyyah.\n\nNeallelne fundamental fundamental inter follow out of genes\nDomynyrovanye and retsessyvnost - typychne Examples allelomorphic interaction of genes. However, in the dish up of growing of the organism distributively and neallelne hen vstupayut in slozhne interaction between themselves.\n\norganism - not mosaics, skladvayuschayasya of action otdelnh and nezavysymh genes and slozhnaya ashes posledovatelnh biochemically and structural processes, opredelyaemh sovokupnostyu genes - genotype\n\n supposition nasledovanye recitation upotreblyayut commonly kak mold expression. In honesty nasleduyutsya no indicant as hen. Signs formyruyutsya individually in the human body of exploitation of the organism, kotore obuslovlyvayutsya genotype and tack of outside environment.
