Chii chinogadzirisa kurara kwomwana?

Zvakaoma kufungidzira upenyu hwemhuri husina vana. Asi kazhinji amai nababa, kana mumwe munhu wavo zvikuru anoda kuve mwanakomana kana mwanasikana. Uye zvino mubvunzo unomuka, chii chinogadzirisa hutano hwemwana uye kana zvichibvira kukonzera mikana yekuberekwa kwemukomana kana musikana vasati vaberekwa. Sezvazvinozivikanwa, mazai evakadzi ane chete X chromosome, asi chirume chinogona kutakura zvose X chromosome uye Y chromosome, muchiyero che 50 kusvika ku50.

Apo mazamu anogadzirwa ne spermatozoon yeboka rokutanga, kusanganiswa kwemakromosomes XX kunowanikwa, izvo zvinoreva kuberekwa kwechecheche. Paunobatanidza XY, unova vabereki vemukomana. Nokudaro, kana iwe uine hanya zvikuru pamusoro pekuti iwe uchave ani, zvakakosha kuti unzwisise kuti chii chinoitwa nemwana wemunguva yemberi.

Zvimwe zvinokanganisa zvepabonde

Panguva yekuita zvepabonde mumudzimai, vakadzi vanobva kune mazana matatu kusvika ku 500 mamiriyoni spermatozoa. Sezvavanowira munharaunda yakaoma, vazhinji vavo vanobva vangofa. Chero bedzi spermatozoa inoramba ichiripo inopona kuburikidza nekushandura kumucheto wemukati, iyo ine zvinyorwa zvishoma, uye inotanga rwendo rwavo kuburikidza nehutachipihu, inotsvaka kudiridza mazai. Icho chiri padanho ichi chakaiswa, ingave mwana achange achida kushambadzira nekodhinda kana kutamba zvidhori.

Kunyange iye zvino munharaunda yezvesayenzi, nharo dzinopfuurira mberi kana hupombwe hwemwana hunoenderana nemurume kana mukadzi, asi kakawanda, vabereki vose vari kunyanya kutarisira avo vachazoberekerwa. Ngationgororei mumamiriro ezvinhu akapi vakomana vanozvarwa kakawanda, uye mune izvo vasikana:

1. Spermatozoa, iyo inotakurisa X chromosome, inofamba zvishoma nezvishoma kupfuura vamwe vavo veY-chromosome vatakuri. Nokudaro, kana kukura kunowanikwa pazuva rekuvhura kana zuva raitevera (14-15 zuva remwedzi unoenderana nemwedzi), ipapo inokurumidza Y-spermatozoa ichasvika pa ovule nekukurumidza kune vavakwikwi X, saka mukomana achazvarwa. Kune rumwe rutivi, ivo vane-X-makwikwi vari nani, saka kana hupombwe hukaitika mazuva mashoma vasati vashandura (12-13th day of the cycle with its normal time), mumwe wavo angangodaro akazadza ovum. Zvadaro zvakakodzera kumirira musikana.
2. Kunyange zvazvo mazuva ano mazita emagetsi anotaura kuti hutano hwomwana hunoenderana zvachose nemunhu, vamwe vanotsvakurudza vanoti amai vanogonawo kukonzera kuti ndiani anoberekwa naye. Kuti uite izvi, iwe unofanirwa kutevedzera pane imwe kudya. Kana mukadzi achirota mudyi wenhaka, anorayirwa kuzivisa zvinhu zvakawanda zvekudya sezvinobvira mukati mekudya, mupunga uye semolina, michero yakaomeswa, mbatatisi, uyewo tei uye alkaline yemaminari emvura. Uye kuitira kuti uve amai vemusikana akarembera kwenguva refu, zvakakosha kupa mhando yemiriwo (kunze kwemamatare), mishonga yemakaka, hove, mazai, sweets, jams, makungu, uyewo kunwa mamwe emaminera emvura anogadzirwa ne calcium. Nokudaro, mhinduro kumubvunzo, kana hutano hwomwana hunoenderana nemukadzi, huchava hwakanaka.
3. Pane chirevo chokuti kana iwe usingave pedyo mwedzi miviri kana mitatu, ipapo musikana achaonekwa. Kana munhu achiita zvepabonde nguva dzose, kuberekwa komukomana kune vakaroorwa vaviri vanovimbiswa.
4. Kudzidza dambudziko revabereki rinoenderana nehutano hwemwana, nyanzvi dzinotarisana nechokwadi chokuti kana mhuri yababa iine vanhu vazhinji, saka, zvichida, zvakakosha kumirira kuberekwa kweanhaka.
5. Zvinotendwawo kuti kana iwe uine pamuviri mumwedzi kunyange wegore (February, April, etc.), ipapo iwe uchava baba vevasikana, asi kana iwe uri kuronga mukomana, zviri nani kuronga mimba kwemwedzi usinganzwisisiki (January, March, etc.). .).
