Qhov sib txawv tseem ceeb ntawm X txuas tseem ceeb thiab X txuas rov qab yog tias X txuas tseem ceeb yog ib qho kab mob caj ces tshwm sim vim muaj cov noob caj noob ces nyob rau ntawm X chromosome thaum X txuas recessive yog kab mob caj ces tshwm sim los ntawm ib qho lossis Ob tug recessive mutant noob nyob rau ntawm X chromosomes.
X txuas dominant thiab X txuas recessive yog ob hom X txuas caj ces qub txeeg qub teg. Qhov qub txeeg qub teg yog vim cov noob nyob rau ntawm X chromosomes. Cov kab mob caj ces tshwm sim vim yog cov noob caj noob ces nyob hauv X chromosomes. Cov poj niam muaj ob X chromosomes, thaum txiv neej tsuas muaj ib tug X chromosome. Hauv cov txiv neej, ib daim qauv ntawm cov noob caj noob ces txaus los ua rau X txuas tseem ceeb lossis X txuas cov kab mob tsis zoo. Tab sis nyob rau hauv cov poj niam, ib daim qauv ntawm cov noob caj noob ces yog txaus los ua rau X linked dominant disorder thaum ob daim ntawv theej ntawm cov noob caj noob ces yuav tsum tau ua rau X linked recessive disorder. Cov poj niam uas muaj ib qho kev hloov pauv hloov pauv hauv ib qho X chromosome yog tus nqa khoom.
X Linked Dominant yog dab tsi?
X txuas dominant yog ib qho teeb meem tshwm sim los ntawm kev hloov pauv hauv cov noob ntawm X chromosome. Tsuas yog ib daim qauv ntawm cov noob caj noob ces txaus rau tus kab mob tshwm sim hauv cov txiv neej thiab poj niam. Qee qhov X txuas nrog cov kab mob tseem ceeb yog ua rau cov txiv neej tuag taus.

X Linked Recessive yog dab tsi?
X txuas recessive yog ib yam mob tshwm sim los ntawm recessive mutant noob nyob rau hauv X chromosomes. Hauv cov poj niam, ob daim ntawv theej ntawm cov noob caj noob ces yog xav tau rau qhov tshwm sim ntawm tus kab mob. Yog tias muaj ib daim ntawv hloov pauv tam sim no, daim ntawv ib txwm tuaj yeem them rov qab rau daim ntawv hloov pauv. Nws tsuas yog tus neeg nqa khoom noj qab haus huv xwb.

Dab tsi yog qhov zoo sib xws ntawm X Txuas Dominant thiab X Txuas Rov Qab?
- X txuas qhov tseem ceeb thiab X txuas cov kab mob tsis zoo tshwm sim vim muaj kev hloov pauv hauv cov noob ntawm X chromosome.
- Ib daim qauv ntawm cov noob hloov pauv txaus los ua rau ob hom kab mob no rau cov txiv neej.
- x kab mob sib kis tsis kis ntawm leej txiv mus rau tus tub.
Dab tsi yog qhov txawv ntawm X Txuas Dominant thiab X Linked Recessive?
X txuas dominant yog kab mob caj ces tshwm sim vim muaj cov noob caj noob ces ntawm X chromosomes. Nyob rau hauv sib piv, X txuas recessive yog ib yam kab mob tshwm sim los ntawm ib los yog ob tug mutant recessive noob ntawm X chromosomes. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm X txuas dominant thiab X txuas rov qab. Tsis tas li, X txuas cov kab mob tseem ceeb muaj tsawg dua li X txuas cov kab mob tsis zoo.
Ntxiv mus, hauv X txuas qhov tseem ceeb, tsuas yog ib daim qauv txaus los ua rau tus kab mob ntawm cov txiv neej thiab poj niam. Nyob rau hauv X linked recessive, ib daim ntawv yog txaus los ua tus kab mob nyob rau hauv cov txiv neej, tab sis ob daim ntawv yuav tsum tau ua rau tus kab mob nyob rau hauv cov poj niam. Li no, qhov no yog qhov sib txawv tseem ceeb ntawm X txuas dominant thiab X txuas rov qab.
Hauv qab infographic tabulates qhov sib txawv ntawm X txuas dominant thiab X txuas recessive rau ib sab ntawm kev sib piv.
Summary – X Linked Dominant vs X Linked Recessive
Cov noob nyob rau ntawm X chromosomes yog lub luag haujlwm rau X txuas qub txeeg qub teg ntawm cov kab mob. X txuas dominant thiab X txuas recessive yog ob yam mob. Hauv X txuas qhov tseem ceeb, ib qho tseem ceeb ntawm cov noob luam ntawm X chromosome ua rau tus kab mob. Hauv X txuas recessive, ib lossis ob daim ntawv theej ntawm cov noob caj ces ntawm X chromosomes ua rau muaj kab mob. X linked recessive disorders muaj ntau tshaj li X txuas dominant. Tsis tas li ntawd, X txuas qhov kev mob tshwm sim ntau dua cuam tshuam rau txiv neej, thaum X txuas qhov tseem ceeb tshaj plaws cuam tshuam rau poj niam. Yog li, qhov no qhia txog qhov sib txawv ntawm X txuas dominant thiab X txuas recessive.
