Kodi genotype? Mtengo wa genotype mu muzochitika sayansi ndi maphunziro

Chibadwa mobwerezabwereza kugunda ife ndi zipambano zawo mu kuphunzira kwa matupi a anthu ndi zina zamoyo. Easy kusamala ndi kuwerengetsera alibe mfundo wamba ndiponso anthu omwe si osauka ndipo sayansi imeneyi.

Kodi genotype?

akuti kudziwa anapereka kwa chibadwa cha chamoyo, chimene mukusungira DNA aliyense wa maselo ake. Lingaliro la genotype ayenera siyanitsa ndi matupi athu ndi, T. Kwa. Mau onse kunyamula lexical tanthauzo losiyana. Motero, matupi mwamtheradi majini onse a mitundu (anthu matupi athu, matupi nyani, kalulu jini).

Kodi genotype wa munthu?

ndi genotype mu zamoyo chiyani? Poyamba ankaganiza kuti chifukwa cha chibadwa losiyana yonse yochepetsetsa. Mfundo imeneyi anali anatsutsa kuyambira asayansi anapeza njira ya mapangidwe a zygote wa gametes awiri: chachimuna ndi chachikazi. Monga chamoyo chilichonse wamoyo ku zygote popangidwa ndi magulu ambiri, n'zosavuta ndikuganiza kuti maselo onse wotsatira adzakhala ndendende akonzedwa yomweyo imene imachititsa.

Komabe, tiyenera kukhala wosiyana wa genotype wa makolo a mwanayo. Ndisanaumbidwe m'mimba liri theka ya majini ndi mayi ake komanso bambo, kotero ana ngakhale ofanana ndi makolo awo, koma pa nthawi yomweyo iwo sali 100% makope.

ndi genotype ndi fenotayipi chiyani? Kodi zosiyana?

Fenotayipi - magulu mbali zonse kunja ndi mkati mwa thupi. Zitsanzo ndi tsitsi, pamaso pa madontho madontho, kutalika, magazi, magazi, kapena kusapezeka kwa kaphatikizidwe enzyme.

Komabe, fenotayipi si chinachake yotsimikizika nthawi zonse. Mukaonera akalulu, mtundu wa ubweya awo mosiyanasiyana malingana ndi nyengo: m'chilimwe iwo ndi imvi ndi yozizira woyera.

Nkofunika kuzindikira kuti m'ndandanda wa majini ndi nthawi zonse, ndi fenotayipi zingasiyane. Ngati ife kuganizira umoyo wa lililonse Gawo limodzi mu thupi, aliyense wa iwo amanyamula ndendende genotype chomwecho. Komabe, insulin ndi apanga chomwechi mu keratin ena, mu akitini lachitatu. Aliyense si ofanana ndi mnzake mu mawonekedwe ndi kukula, ntchito. Zimenezi zimatchedwa mawonetseredwe phenotypic. Ndicho chimene genotypes ndi zooneka ndi amasiyana fenotayipi lapansi.

zodabwitsazi anafotokoza chifukwa chakuti zosiyanasiyana maselo nyongolosi ena majini m'gulu ntchito, pamene ena mu "mode tulo." Recent kapena moyo kukhala wofooka, kapena kachiwiri ntchito ndi khungu mu mavuto.

Zitsanzo kujambula genotypes

Zochita kuphunzira zambiri majini ikuchitika ntchito kubisa makonzedwe chibadwa. Mwachitsanzo, zofiirira diso jini kwalembedwa ndi likulu "A" ndi mawu a diso buluu - kalata zazing'ono "ndi". Choncho zikusonyeza kuti chizindikiro cha lalikulu bulauni-eyed ndi buluu - mavuto a.

Choncho, pamaziko a anthu akhoza kukhala:

• homozygotes lalikulu (AA, Brown-eyed);
• heterozygotes (AA, zofiirira-eyed);
• homozygotes recessive (AA, maso a buluu).

Malinga ndi mfundo imeneyi ankachita phunziro pakati majini iwo wokha, amangoona ntchito awiriawiri angapo chibadwa. Izi zikutipatsa funso lakuti: kodi genotype 3 (4/5/6, etc ...)?

mawu Izi zikutanthauza kuti atengedwa kamodzi awiriawiri jini atatu. analembedwawo Mwachitsanzo, motere: AaVVSs. Pali majini latsopano kuti ali ndi udindo makhalidwe osiyana kwambiri (mwachitsanzo, molunjika tsitsi ndi tsitsi lopotana, pamaso pa mapuloteni kapena kupanda kwake).

N'chifukwa chiyani kulowa lililonse genotype makonzedwe?

jini iliyonse, anapeza asayansi, ndi dzina yeniyeni. Nthawi zambiri ndi mawu English kapena mawu amene angafikire kukula ndithu m'litali. Kalembedwe maina zovuta kuti anthu a sayansi yachilendo, kotero asayansi anayambitsa kuposa kujambula yosavuta chibadwa.

Ngakhale mkulu sukulu zina mukudziwa chimene genotype 3a. Chotero kulowa ndi limasonyeza kuti jini amachititsa alleles 3 jini chomwecho. Pamene ntchito dzina ili Gene kumvetsa mfundo chibadwa zikhoza kukhala zovuta.

Pankhani Laboratories kumene kuphunzira mwakhama karyotype ndi DNA maphunziro, kumeneko ayamba mayina boma la chibadwa. Izi ndi zoona makamaka kwa asayansi amene amafalitsa anapeza.

genotypes Kodi applicable

Chinthu china zabwino kugwiritsa ntchito zizindikiro zophweka - amagwiritsidwa ntchito mwanjira imeneyi. Zikwi majini ndi dzina lapadera, koma aliyense wa iwo akhoza ayenela kuimilidwa ndi kalata imodzi yokha ya zilembo. Nthawi zambiri kuthetsa mavuto majini pa mbali zosiyanasiyana makalata mobwerezabwereza mobwerezabwereza, nthawi iliyonse decrypted phindu. Mwachitsanzo, mu vuto la jini B - wakuda ndi mtundu wa tsitsi, ndi zina - ndi kukhalapo kwa timadontho-timadontho.

Funso lakuti "kodi genotypes a" akuwuka osati m'kalasi kwa zamoyo. Ndipotu Chizindikiro amachititsa amaona mawu ndi terminology mu sayansi. Ziri kulankhula, ntchito genotypes - chitsanzo masamu. Mu moyo weniweniwo kovuta ngakhale kuti mfundo onse akadali anakwanitsa kusamutsa pepala.

Mokulira ndi genotypes mu mawonekedwe zimene tikudziwa iwo, ntchito pulogalamu ya sukulu ndipo maphunziro apamwamba kuthetsa mavuto. Zimenezi zimatithandiza kumvetsetsa nkhaniyo "zimene genotypes" ndipo umakula mphamvu ophunzira kuti tisanthule. M'tsogolo, luso la ntchito timva amenewa ndi zothandiza, koma mawu enieni ndi mayina a chibadwa yoyenerera kwambiri kufufuza enieni.

Panopa, majini ndi kuphunzira mu Laboratories zosiyanasiyana kwachilengedwenso. Kubisa ndi ntchito genotypes n'kofunika kuti zokambiranazo zachipatala, pamene mbali imodzi kapena zingapo zimene gwero zingapo za mibadwo. Pa linanena bungwe la akatswiri anganeneretu phenotypic mawonetseredwe mu ana ndi Mwina ena (mwachitsanzo, maonekedwe a 25% lagolide kapena 5% ana obadwa ndi polydactyly).
