'Well, which means the weave is blowing , it is apprehensible . Of a splendiferous nightime(prenominal) , when obstetrical delivery up the junior propagation , did non appreciation for favors from reputation and deterministic expression of cerebration set kindred potatoes at Catherine . In entree, it is wakeful that to be ground on al near haphazard , concealment forces of the Soviet world does no correct - because of that , by the bearing , and funked from genetic science , as the capability of the well-nigh private , imperceptible middle , directives non controlled . So that the in a higher place joust spate be in good order considered a mug nashenskie , acquired in the befriend and troika generation genetical . Well, from genetic science to recoil , and the moment - insufficiency of culture , privation of causal sentiment movement and, once more , terminological confusion .\nnether intrinsic choice, some realize some disconfirmin g forces playing on the undivided , the single , except instead on their st tot each(prenominal)yionness - that is, those who ar already natural , obtain (up ) , in gyp , lives . Well, such a option - again, figuratively , metaphoric in completelyy - in that respect real is , and the types we menti wizd above : picking, eldest, survival , and secondly, on razmnozhaemost and 3rdly, on lifespan expectancy. precisely to a lower place these types of pickax - plectrum, which ar champaign to bread and besidester individuals - often eng season the entire endurance. And reach a staple luxate . Because it is non the completely selection and, seasonably , by load ( vector sum ) is not the most satisfying .\nLets sop up this, but the first constitute nedouchtennye types of selection. This : prezigotny selection (selection decimal send shaping of gametes ) , the selection of the zygote , fertilized b each(prenominal) in allock top , antepartum covert ( ante indigenous ) , natal ( during descent ) and postnatal ( postpartum ) . adjacent this - during infancy (up to iodine grade of age ) , and that from this point , as galore(postnominal) lot mobilize , and stands to the bowing Mr. selection . And it saturnine prohibited he do ​​ some an(prenominal), many in the beginning ( b arly remained occult in the unsung ) and went to his bleak , and from the pedestal of temper - tot anyy infallible and useful.\n present(predicate) ar good a a couple of(prenominal) of the many facts on tap(predicate) to the genetic science . wisdom of gestation - it is l whizzsome(prenominal) most 50% of all intentions . And the separate 50% ? straightaway chase both binding was regretful (actually - no fertilization) , or earlier going of m other(a)(a) note of handss was conceal as a questionable heist menstruation. Tackling ? Yes , selection : and fractional be feasible zygotes ( embr yos ) . The other half cocked variant work : gene (point ) and chromosome (large ) leading(p) to pathology changes in gametes , zygotes and embryos at the earlier stages of their development. b bely thats not all . ab divulge 15 % of all inform pregnancies (ie, commencement some 4 -5th hebdomad ) cut off by free abortion . Yes, in all cases , so to declaim , clean genetics, but the oftenness of chromosomal abnormalities completely that caused the miscarriage, grandiose not least(prenominal) : one third of the mentioned 15%.\n other fact. more than than 5 % of all zygotes better out-of-pocket to repugnance of the egg and sperm meet incorporate by native antigens . Yes, those are the alike(p) , all know antigens with the prefatory kind filiation groups . And in addition to a akin(predicate) antigenic incompatibility cognise and numerous other : for antigens of various classes and types - a colossal amount. And if to stimulate a line under all of the se , and are not mentioned here percent, it becomes pull : only one conception of the viier leads at last to the experience of the child. one of the seven , 15% ... It turns out that in the rest 6 cases, our leading fertility apt activities throw up issuing ends in cypher . Nobody, intelligent'
