Cov neeg tsim kho kab mob - kab mob ntawm tes , ib yam mob uas cov ntshav liab hlwb yog qhov txawv txav, yog tias lawv tau txais ob daim ntawv theej ntawm cov noob rau cov pa oxygen-carrying protein hemoglobin. Cov noob faulty txuas ntxiv mus vim tias txawm nqa ib daim qauv ntawm nws muaj qee qhov kev tiv thaiv mob malaria.

Kuj tseem paub yog, malaria puas cuam tshuam rau cov neeg mob mob qog noj ntshav?

Kev nkag siab Sickle - Cell Heterozygotes rau lub cev kab mob cell noob kuj tiv thaiv mob malaria , thaum cov neeg mob uas yog homozygous rau cov kab mob cell gene, raug kev txom nyem los ntawm kab mob kis kab mob thiab muaj feem cuam tshuam rau kev tuag taus ntawm mob malaria.

Kuj Paub, qhov kev sib txuas ntawm sickle cell anemia thiab malaria quizlet yog dab tsi? - Cov neeg muaj ob kab mob cell alleles muaj evolutionary kom zoo dua vim lawv tsis tau kab mob cell kab mob los yog kis tau mob malaria . - Cov tib neeg uas muaj ob qho tib si hemoglobin alleles tau txais ob qho tib si kab mob cell kab mob thiab raug rau mob malaria , yog li cov alleles raug tshem tawm ntawm cov pej xeem.

Yog li ntawd, Sickle Cell puas hloov mus rau malaria?

Natural Selection: Uncovering Mechanisms of Evolutionary Kev kho kom haum mus rau Kab Mob Sib Kis. Lub evolutionary txuas ntawm kab mob - cell qhov zoo thiab mob malaria kev tawm tsam qhia tias tib neeg tuaj yeem ua tau thiab ua tau yoog raws . Allison tau sau tseg ntxiv tias cov neeg uas nqa lub kab mob - cell qhov zoo tau resistant rau mob malaria (Allison, 1954).

Vim li cas cov neeg mob mob khaub thuas tsis tuaj yeem kis tus kab mob malaria?

Cov neeg txhim kho kab mob - cell kab mob, ib yam mob uas cov ntshav liab hlwb yog qhov txawv txav, yog tias lawv tau txais ob daim ntawv theej ntawm cov noob rau cov pa oxygen-carrying protein hemoglobin. Lawv cov txiaj ntsig tau pom tias cov noob tsis tiv thaiv kab mob los ntawm tus kab mob mob malaria parasite, raws li yav tas los xav.
