Artificial xaiv xaiv rau qhov zoo uas twb muaj lawm hauv a hom, hos genetic engineering tsim tej yam tshiab. Hauv kev xaiv dag , cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov tau qhov zoo hauv pej xeem. Evolution tau tshwm sim.

Xav txog qhov no, dab tsi yog qhov downside ntawm kev xaiv khoom tsim raws li daim ntawv ntawm genetic engineering?

Xaiv yug me nyuam (tseem hu ua kev xaiv dag ) yog cov tsoos tshaj plaws daim ntawv ntawm genetic engineering , tab sis nws muaj nws downsides . Cov txheej txheem yog qeeb thiab nyuaj thiab feem ntau ua rau tsis xav tau kev phiv, xws li amplification ntawm deleterious recessive noob.

Dab tsi yog hom kev xaiv dag? Darwin peb Hom ntawm Kev xaiv . Hauv Kev Hloov ntawm Tsiaj thiab Nroj Tsuag Hauv Tebchaws, Darwin (1868) suav tias yog ob hom kev xaiv khoom cuav ntxiv rau ntuj xaiv 1: txheej txheem xaiv thiab tsis nco qab xaiv . Raws li nws tau piav qhia (Darwin 1868, p.

Ib yam li ib tug yuav nug, nws txhais li cas los ua ib qho kev xaiv khoom cuav?

Artificial xaiv yog txhob txwm yug tsiaj los yog tsiaj txhu. Nws txhais tau tias tib yam li kev xaiv yug me nyuam thiab yog ib txoj hauv kev qub ntawm genetic engineering. Kev xaiv yug me nyuam yog ib txoj kev siv thaum yug tsiaj yug tsiaj, xws li dev, nquab lossis nyuj.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kev xaiv yug me nyuam thiab genetic engineering?

Muaj qee yam zoo sib xws , txawm li cas los. Piv txwv li, ob qho tib si genetic engineering thiab Xaiv yug me nyuam tshwm sim hauv kev hloov kho genotype ntawm lub cev. Hauv lwm lo lus, lub cev noob hloov nyob rau hauv ib txoj kev. Yog ib los yog ntau tshaj noob los ntawm lwm hom yog qhia, qhov tshwm sim genome muaj cov DNA recombinant.
