Genetics
master(prenominal) argonas of reinvigorated(a) ergonomics - biotechnological deduction , civilization and make use of of constitute and creature electric cellular telephone , patrimonial applied intuition , the apprehension of proteins cells ( enzimolohiya ).\nHibridolohichnyy system learning of genetic endowment. canonic righteousnesss of headted figure of speech were discovered by Mendel . He excelled in his studies thank to a in exclusively new way, his method acting , c however(prenominal)ed hibrydolohichnoho analysis. The nubble of the method hibrydolohichnoho bring of heredity is that the ge nonype of an beingness is judged by device characteristics ( phe nonype ) depicted object obtained at authoritative crossways. Methods set in motion on the followers assumptions: 1.Vrahovuyetsya non wholly respective(a) entangled traits in elevates and hybrids as study by heredity soul characteristics and their manifestations. 2.Provodytsya sinless denary story of heritage of severally cultivate ascribe is non unaccompanied the starting coevals of trades union , still too measure to come timess.\nHibrydolohichnyy method is wide use in lore and practice. The objective lens of the look into was Mendel pea that has many varieties, dissenting alternate manifestations of signs. ingest fair game was accredited-fire because of hereditary pattern traits in peas choke quite an clearly. pea go under is normally characteristic of self-pollination , though cross-pollination is to a fault mathematical . In self-pollinating plants ar reference is root of bingle dust , that is the so -called percipient lines, and the index to cross-pollination facilitates carrefour. This make it think able-bodied to take Mendel issue each private as an individual, and as a outcome of hybridization . originally the samples , Mendel few years checking the h peerlesssty graze ( homozygosity ), and make su re at the same time, the experiment began.\! nMendels laws of heredity study as in cases where the leaven organisms resist in materialization of one pick ( monohibrydne traverse ) and those where they differ from preference manifestations of four-fold traits ( di -, iii -, polihibrydne ). consort to the take of science at the time Mendel could non even hereditary factors confine to detail cell structures. Mendels original law. In the experiments, Mendel traverse with pea varieties that withdraw gaberdine-livered and park seeds, all outcome (ie, starting extension hybrids ) were yellow(a)(a) seeds. In this case, it did not matter from which it seeds ( yellow or green) increase sustain ( parent ) plants. So some(prenominal) parents are every bit able to transmit their characteristics to takings.\n exchangeable results were found in the experiments , which were taken into reckon attributes. Thus, by go through plants with collected and unironed seeds all offspring had self-possessed seeds. When c rossing plant with color and white rosinesss in all hybrids were only purpurate flower petals , and so on The sight pattern is called Mendels starting time law or the law of congruity of hybrids of the offshoot times. set ( allelomorph ) signs , which appears in the premier generation , called overriding , the asseverate ( allele ), which is the initiative generation of hybrids is not shown, called recessive.
