Recessive yog hais txog ib hom allele uas yuav tsis tshwm sim hauv ib tus neegtshwj tsis yog tias ob tus tib neeg cov ntawv luam ntawm cov noob muaj qhov tshwj xeeb genotype.

txhais li cas los ntawm recessive?

Refers to ib yam uas qhia tsuas yog thaum genotype yog homozygous; ib qho kev zoo uas zoo li yuav npog los ntawm lwm yam khoom qub txeeg qub teg, tseem muaj nyob rau hauv cov pej xeem ntawm heterozygous genotypes. © Nature Education.

Yuav ua li cas thiaj tau txais cov noob caj noob ces?

Yuav kom muaj tus kab mob autosomal recessive, koj tau txais ob lub noob hloov pauv, ib qho los ntawm txhua tus niam txiv. Cov kab mob no feem ntau kis tau los ntawm ob tus neeg nqa khoom. Lawv txoj kev noj qab haus huv tsis tshua muaj kev cuam tshuam, tab sis lawv muaj ib qho kev hloov pauv (gene recessive) thiab ib lub noob qub (cov noob tseem ceeb) rau tus mob.

Vim li cas thiaj hu ua noob caj noob ces?

Nyob hauv ib khub ntawm autosomal chromosomes, muaj ob daim ntawv luam ntawm txhua tus noob, ib qho los ntawm txhua tus niam txiv. Yog tias ib qho ntawm cov noob no txawv txav, lwm tus yuav tsim cov protein kom txaus kom tsis txhob muaj kab mob. Thaum qhov no tshwm sim, qhov txawv txav yog hu ua recessive.

Yim piv txwv ntawm cov noob caj noob ces yog dab tsi?

Recessive alleles tsuas yog qhia lawv cov txiaj ntsig yog tias tus neeg muaj ob daim ntawv theej ntawm allele (tseem hu ua homozygous?). Piv txwv li, allele rau lub qhov muag xiavyog qhov tsis txaus, yog li kom muaj qhov muag xiav koj yuav tsum muaj ob daim ntawv ntawm 'xiav qhov muag' allele.
