Noob caj noob ces khawv koob Yuav tej yam yees siv powers Garri Pottera yuav tsum tau sau nyob rau hauv nws DNA?

Nyob rau hauv lub ntiaj teb no ntawm "Harry Potter" khawv koob muaj peev xwm tso cia. Witches thiab wizards muaj cov niam txiv uas tseem muaj tej yam yees siv powers, thiab lawv cov pog yawg. Cuaj kaum, muaj kev zam rau txoj cai no. Piv txwv li, Germiona Greyndzher tau yug los rau ib tug khub ntawm Muggles (cov neeg uas tsis tej yam yees siv powers), thiab cov neeg nyob ze nyob rau hauv lub chav Harry Seamus Finnigan yog tus tub-muggle txiv thiab ib tug Irish dab.

Tab sis tej zaum witches thiab wizards khub niam txiv muaj cov me nyuam tsis muaj tej yam yees siv powers, uas yog hu ua ib tug squib. Cov no yog, piv txwv li, lub observer "Hogwarts" Argus Filch lossis neeg zej zog Harry Arabella Figg. Raws li koj tau pom, cov khawv koob muaj cai ntawm qub txeeg qub teg, tab sis yog dab tsi caj yam piav vim li cas ib txhia yog yug witches los yog wizards, thaum lwm tus neeg tsis muaj tej yam yees siv powers?

Nws yog lo lus nug no txiav txim siab mus kawm Eric Span - pab xibfwb txog biology ntawm Duke University nyob rau hauv North Carolina, uas muaj ib tug kev sib tham nyob rau hauv no lub npe.

recessive noob

Noob caj noob ces yuav muab cov lus teb rau cov lus nug ntau nyob rau hauv tej yam yees siv lub ntiaj teb no ntawm "Harry Potter", thiab tsis tsuas mus rau piav qhia txog cov khawv koob ntawm nws heroes. Piv txwv li, cov plaub hau xim Weasley tsev neeg yuav piav tau noob caj noob ces. Liab cov plaub hau yog tshwm sim los ntawm ib tug kev hloov nyob rau hauv lub MC1R noob. Txawm li cas los, qhov no yog ib tug recessive kev zoo losis phem, piv txwv li nws manifests nws tus kheej xwb nyob rau hauv lub rooj plaub uas lub hloov yog tam sim no nyob rau hauv ob qho tib si poob lawm ntawm DNA, uas yog pub tus me nyuam. Raws li Arthur thiab Molli Uizli liab, lawv cov me nyuam tau txais ob daim ntawv ntawm cov noob hloov thiab kuj yug los nrog liab cov plaub hau.

Cuaj kaum, nyob rau hauv lub kawg scene ntawm lub xeem movie, "Harry Potter thiab cov deathly Hallows: Part 2", peb pom tias Lily - tus ntxhais hluas ntawm Harry thiab Ginny - raws li liab plaub hau, txawm tias lawv yog tsaus, Harry. Qhov no txhais tau tias Harry tau pub ib daim qauv ntawm cov kev hloov los ntawm nws niam, uas yog tseem liab, thiab muab nws mus rau nws tus ntxhais. Txawm tias muaj tseeb hais tias Harry tau txais los ntawm nws niam ib tug recessive noob liab plaub hau, nws tau yug los nrog cov plaub hau dub li nws txiv James tsis muaj no hloov. Yog li, lub recessive noob manifested xwb tus ntxhais ntawm Harry thiab Ginny.

hom noob

Yog khawv koob noob yog tseem recessive, raws li nyob rau hauv cov ntaub ntawv nrog rau cov liab cov plaub hau? Raws li spans, Hagrid - forester nyob rau hauv "Hogwarts" - proves conclusively tias nws tsis yog. Lub Giants tsis muaj tej yam yees siv powers, thiab Hagrid tau yug los nyob rau hauv lub tsev neeg ntawm ib tug niam thiab ib tug giant wizard txiv. Yog li, tsuas daim ntawv ntawm cov khawv koob ntawm cov noob yog dhau los ntawm tus txiv rau nws, thiab yog li ntawd nws lub hom, tsis recessive.

autosomal yam ntxwv

Qhov kev piv txwv mas, yuav tau alluding mus rau lub fact tias cov tej yam yees siv powers txuam nrog ib tug Y-chromosome, uas yog cov khawv koob noob yuav tsum kis tau rau ntawm leej txiv lub DNA (maum muaj ob tug X chromosomes, thaum cov txivneej muaj ib tug X thiab Y- chromosomes). Cuaj kaum, Seamus Finnigan txiv yog ib tug Muggle thiab nws niam yog ib tug poj dab, ces nws tej yam yees siv powers yuav tsis kis tau los ntawm cov Y-chromosome. Raws li Span puas autosomal tej yam yees siv peev xwm, uas yog tsis muaj feem xyuam rau kev sib deev yam ntxwv. Yog li, peb yuav xaus uas cov khawv koob noob yog autosomal thiab hom.

random hloov

Nws yuav zoo li hais tias txhua yam yog yooj yim, tab sis, yog hais tias tsev neeg yuav tshwm sim Muggle wizards? Yog hais tias qhov no yog ib tug tseem ceeb kev zoo losis phem, ces qhov twg puas tau cov khawv koob Hermione, vim hais tias nws yog tus thawj dab nyob rau hauv lub tsev neeg? Hermione yog ib qho piv txwv ntawm kev tshuaj ntsuam genetic hloov de novo, uas zoo nkaus li rau thawj lub sij hawm vim muaj ib tug kev hloov nyob rau hauv lub qe los yog cov phev, los yog hauv lub embryo tom qab fertilization. Thiab qhov no hom ntawm kev hloov yog heev nyob rau hauv lub neej tiag tiag.

Tej random change yuav piav tau li cas ib tug tsev neeg ntawm ob wizards yuav tau yug ib tug squib. Yog hais tias cov khawv koob noob ua hauj lwm kom zoo, nws tsim muaj tej hom ntawm cov protein. Phenotype, los yog lub observable yam ntxwv tshwm sim los ntawm qhov kev ua yog tej yam yees siv powers. Tab sis, yog hais tias koj muaj no noob hloov (Span npaj siab mus hu nws ib tug hloov Squib), muaj lwm yam uas muaj protein ntau uas alters cov khawv koob noob. Yog hais tias cov DNA ntawm ib tug niam txiv yog ib daim ntawv SQUIB hloov, nws yuav lov tes taw tej yam yees siv protein uas yuav tsis tso cai rau cov me nyuam tsim muaj lub peev xwm los khawv koob.

Ib yam li ntawd, zaum tam sim no muaj peev xwm hloov lub noob ntawm txiv hmab txiv ntoo yoov, xa mus rau lub manipulation ntawm roj ntsha zoo nyob rau hauv Feem ntau, es lub noob ntawm cov khawv koob, raws li tau piav los ntawm Dr. Span.

Yuav ua li cas txiav txim lub hwj chim ntawm magicians

Tab sis muaj lwm lo lus nug: yog vim li cas ib co witches thiab wizards pom tau hais tias ntau haib tshaj rau lwm? Peb hu qhov no ib tug neeg variations tej yam yees siv peev xwm? Thiab seb nws yuav piav qhia txog noob caj noob ces? Zaum hais tsis yeej.

Xav txog tej yam ib tug me nyuam uas nws niam thiab txiv muaj ib tug "basketball" txoj kev loj hlob. Tus me nyuam yuav tau txais nws, tab sis nws tsis lav hais tias nws yuav ntse ua si basketball. Yog li, caj tsis tau lees tias koj zoo heev txawj. Qhov kev paub thiab lub zog ntawm Hermione, raws li zoo raws li lub peev xwm coj Weasley yog tsis lig nyob rau ntawm noob caj noob ces.

Thaum xaus ntawm lub rooj sib tham yog ib tug ntawm cov neeg koom nug Dr. Span rau dab tsi, nyob rau hauv nws lub tswv yim, cov kws qhia ntawv ntawm nws yuav xa ib tug "Sorting Hat". "Nyob rau ntawm 100% nyob rau hauv" Slytherin, "los yog, raws li kuv hu xov tooj rau nws," Management "," - said Span.
