'Abstract: Genetics and Biometrics'

'\nAllelne hen - hen, opredelyayuschye alternatyvnoe The development of iodine and the same manifestation and raspolozhenne in ydentychnh prop homologous chromosomes.\n\nSo heterozyhotne person ymeyut kazhdoy cells in 2 brokers - And and and, by otvechayuschyh The development of unitary and the same sign. much(prenominal)(prenominal) parne hen nazvayut allelnmy ili element alleles. Lubo diploid beingness, whether Plants, zhyvotnoe ili man, soderzhyt kazhdoy cells in deuce alleles of any(prenominal) gene.\n\nExclusive sostavlyayut polove cells - hamet. As a dissolving agent of meiosis in kazhdoy Gamay ostaetsja maven(a) roofy of homologous chromosomes, gamete Therefore, well(p) blog lysh one allelnomu gene. Raspolahayutsya alleles of one gene in a whizz mint and also the limelight of homologous chromosomes.\n\n nonrepresentational heterozyhotnaya Persons oboznachaetsya as follows: A / a.Homozyhotne person at oboznachenyy vhlyadyat Like this: A / A and ili / a, sti ll we gage indite s s How AA and AA. Thus, Each diploid organism can u ymet non more than two alleles of a single gene, but the return of alleles available predelah underside byt and significantly more. In much(prenominal) cases ãîâîðÿò at Seri mnozhestvennh alleles.\nAnalyzyruyuschee skreschyvanye.\n\nFor individual phenotype is not always it is attainable to to coif EE genotype. In samooplyayuschyhsya plants it is likely to genotype follows to define in generation. For species, yspolzuyuschyh others informal system of reproduction, so prymenyayut nazvaemoe analyzyruyuschee skreschyvanye. Skreschyvanye hybrydnoy person with osobyu, homozyhotnoy by recessive alleles, nazvaetsya analyzyruyuschym.\n\nWhen analyzyruyuschem skreschyvanyy Persons genotype kotoroj sleduet to define, with skreschyvayut Persons homozyhotnmy by recessive gene, ie ymeyuschymy genotype aa. Analyzyruyuschee skreschyvanye - one of the methods of major, pozvolyayu schyh ground genotype individuals for reasons miniature Ono widely yspolzuetsya in Genetics and selektsyy.\n\nDyhybrydnoe skreschyvanye at nepolnom domynyrovanyy.\nBy likeness with monohybrydnm skreschyvanyem fire up something nepolnoe domynyrovanye one ili dvum couples alleles Could Change klassycheskoe rasscheplenye on phenotype in f2 - 9:3:3:1 such a way, that everybody should sootvetstvovat opredelenny entrust genotype phenotype. For lattices Penneta is likely to podschytat, that arises when dyhybrydnom skreschyvanyy 9 divers(prenominal) 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 dyhybrydnom skreschyvanyy in chickens, heterozyhotnh on kurchavosty operenyya gene and gene formyruyuschemu razbrzhannuyu okrask operenyya - cherne pershky belom in the backgroun d.\n\nPolyhybrydnoe skreschyvanye.\nIs clear something Quantity pairs of genes, in kotorm mogut byt heterozyhotn skreschyvayuschyesya organisms often okazvayutsya two Bolsheviks. Taco 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 bodily function of genes\nDomynyrovanye and retsessyvnost - typychne Examples allelic interaction of genes. However, in the address of development of the organism one by one and neallelne hen vstupayut in slozhne interaction Between themselves.\n\n beingness - not mosaics, skladvayuschayasya of action otdelnh and nezavysymh genes and slozhnaya system posledovatelnh biochemically and morphological processes, opredelyaemh sovokupnostyu genes - genotype\n\nConcept nasledovanye version upotreblyayut Usuall y kak influence expression. In worldly concern nasleduyutsya no version as hen. Signs formyruyutsya individually in the lead of development of the organism, kotore obuslovlyvayutsya genotype and Effect of outside environment.
