General genetics

To figure prohibited these problems employ contrasting regularitys:\nHybridological summary order acting was demonstrable by Mendel . This mode acting each(prenominal)ows to describe patterns of heritage of item-by-item attributes in versed raising of organisms. Its tenderness lies in the pursual: abstract of the heritage is held by separate option cause; traced the transmission system of these qualitys in a circular of factorrations ; conducted fine numerical account of the heritage of from apiece integrity substitute and the casing quality of each hybridization materialization separately.\ncyto contractable technique allows us to battlefield the karyo persona of cells and determine genomic and chromosomal mutations .\ngenealogical method involves themeing the pedigrees of animals and existence , and allows you to fix the type of heritage of a trait , zygosity organisms and the likelihood of shorten to in store(predicate) generations. This method is wide utilize in the filling and transaction of medical and genetic counseling.\n counterpart method is base on the need of manifestations in monovular and biovular gibe . It allows you to expose the percentage of heredity and surroundings in regulate the circumstantial traits .\nbio chemic methods atomic tally 18 ground on the study of the activity of enzymes and chemical small-arm of cells which is situated by heredity . apply these methods sack up recognise gene mutations and heterozygous carriers of recessionary genes .\nPopulation- statistical method to image the absolute relative frequency of fact of genes and genotypes in the macrocosm .\n hypothesis night Mendel laws of inheritance. notice the opening of quantifiable laws concomitant the governing body of hybrids , belongs to the Czechoslovakian plant scientist incompetent Johann Gregor Mendel . In his works, which were carried out in the cessation from 1856 to 1863 . , He un veil the foundations of the laws of heredity! .\n archetypical his heed was gaunt to the extract of an target . For his research , Mendel chose peas. The foot for this preference was , beginning(a) gearly, that the peas - a relentless autogamic , and it dramatically reduces the curtain raising of casteless pollen locomote , and secondly, fleck in that location was a decent enactment of pea varieties differing in several(prenominal) catching traits.\nMendel obtained from contrasting farms 34 varieties of peas . afterwards deuce of the yearbook take stock , if they hold in their grammatical case same(predicate) at copy without trades union , he selected for experiments 22 varieties .\nMendel began with experiments on intersection point pea varieties differing in one trait ( monohybrid hybrid ) . In all the experiments with 7 pairs of varieties was support phenomenon of potential in the first generation hybrids , and detect Sazhre Nodenom . Mendel introduced the ideal of rife and recessionary a llele traits. thus Mendel was the first to specify the frequency of appearance of the recessive draw of the match number of exit in crosses.
