Ntau yam tuaj yeem ua rau muaj kev sib txawv ntawm kev loj hlob thoob plaws thiab ntawm cov pejxeem xws li yam tseem ceeb ntawm caj ces , khoom noj khoom haus, ib puag ncig tej yam kev mob, kev sib raug zoo tej yam kev mob, thiab kab lis kev cai tej yam kev mob. Genetic Factors : Genotype tuaj yeem muaj txiaj ntsig zoo rau kev loj hlob raws li qhia hauv ob qho piv txwv tom ntej.

Kuj nug, dab tsi yog qhov ua rau muaj kev hloov pauv?

Major ua rau ntawm kev hloov pauv muaj xws li kev hloov pauv, noob ntws, thiab kev sib deev. DNA mutation ua rau caj ces kev hloov pauv los ntawm kev hloov cov noob ntawm tib neeg hauv cov neeg. Gene flow ua rau muaj caj ces kev hloov pauv raws li cov neeg tshiab nrog cov noob sib txawv sib txawv txav mus rau hauv cov pej xeem.

Tsis tas li ntawd, 2 hom kev hloov pauv yog dab tsi? Hom Variation Variation nyob rau hauv ib hom yog tsis tshua muaj, tab sis yeej muaj ob hom loj ntawm kev hloov pauv nyob rau hauv ib hom: nruam kev hloov pauv thiab tsis txuas ntxiv kev hloov pauv . Tsis tu ncua kev hloov pauv yog qhov txawv hom kev hloov pauv muab faib rau ntawm qhov txuas ntxiv.

Kuj tseem yuav paub, dab tsi yog yam uas cuam tshuam txog kev hloov caj ces?

Genetic variation tuaj yeem tshwm sim los ntawm kev hloov pauv (uas tuaj yeem tsim cov alleles tshiab hauv cov pejxeem), random mating, random fertilization, thiab recombination ntawm homologous chromosomes thaum lub sij hawm meiosis (uas reshuffles alleles nyob rau hauv lub cev xeeb tub).

Kev hloov pauv hauv evolution yog dab tsi?

Kev hloov pauv , hauv biology, txhua qhov sib txawv ntawm cov hlwb, cov kab mob ntawm tus kheej, lossis pab pawg ntawm cov kab mob ntawm ib hom kab mob tshwm sim los ntawm kev sib txawv ntawm caj ces (genotypic kev hloov pauv ) lossis los ntawm kev cuam tshuam ntawm ib puag ncig yam ntawm qhov kev qhia ntawm cov caj ces muaj peev xwm (phenotypic kev hloov pauv ).
