Keeb kwm ( h 2 ) yog additive caj ces variance faib los ntawm phenotypic variance, (5.1) h 2 = σG2σP2, uas yog qhov tseem ceeb quantifies caj ces pab txhawb rau qhov qhia txog qhov zoo.
Tsis tas li lo lus nug yog, yuav ua li cas h2 heritability xam?
Keeb kwm yog qhia raws li H2 = Vg/Vp, qhov twg H cuab yeej cuab tam kwv, Vg variation nyob rau hauv genotype, thiab Vp variation nyob rau hauv phenotype. Keeb kwm kwv yees muaj nyob rau hauv tus nqi ntawm 0 mus rau 1.
Tsis tas li ntawd, qhov txawv ntawm qhov kev nkag siab nqaim h2 thiab kev nkag siab dav dav h2 yog dab tsi? Cov dav - kev paub cuab yeej cuab tam yog qhov piv ntawm tag nrho cov noob caj noob ces sib txawv rau tag nrho phenotypic variance. Cov nqaim - kev paub cuab yeej cuab tam yog qhov piv ntawm additive genetic variance rau tag nrho phenotypic variance.
Kuj kom paub yog, dab tsi yog txhais los ntawm kev cuab yeej cuab tam?
Keeb kwm yog ib qho kev txheeb cais siv nyob rau hauv thaj chaw ntawm kev yug me nyuam thiab noob caj noob ces uas kwv yees qhov kev hloov pauv ntawm cov phenotypic zoo nyob rau hauv cov pejxeem uas yog vim muaj kev hloov pauv ntawm caj ces ntawm cov tib neeg hauv cov pejxeem.
Dab tsi yog lwm lo lus rau cov cuab yeej cuab tam?
(kuj noob caj noob ces), yug, yug, qub txeeg qub teg , tau qub txeeg qub teg.

Dab tsi yog ob qho laj thawj tseem ceeb ntawm kev mob caj ces hauv tib neeg?
Muaj peb hom kab mob caj ces: Ib hom kab mob ib leeg, qhov kev hloov pauv cuam tshuam rau ib lub noob. Sickle cell anemia yog ib qho piv txwv. Chromosomal disorders, qhov twg chromosomes (los yog ib feem ntawm chromosomes) ploj lawm los yog hloov. Cov kab mob nyuaj, qhov twg muaj kev hloov pauv hauv ob lossis ntau lub noob
Dab tsi yog kev sib pauv caj ces hauv cov kab mob?
Bacterial gene exchange txawv ntawm eukaryotes: Cov kab mob tsis pauv cov noob los ntawm meiosis. Cov kab mob feem ntau pauv me me ntawm genome, ob peb lub noob ntawm ib lub sij hawm, los ntawm kev hloov pauv, hloov pauv, lossis sib txuas. Hloov ntawm hom, txawm lub nceeg vaj, yog ib txwm muaj; tsawg dua hauv eukaryotes, txawm tias nws tshwm sim
Dab tsi yog qhov kev kuaj hla hauv cov noob caj noob ces?
Nyob rau hauv cov noob caj noob ces, ib qho kev sim hla, thawj zaug qhia los ntawm Gregor Mendel, koom nrog kev yug me nyuam ntawm ib tus neeg nrog phenotypically recessive tus neeg, txhawm rau txiav txim siab zygosity ntawm yav dhau los los ntawm kev txheeb xyuas qhov feem ntawm cov xeeb ntxwv phenotypes. Zygosity tuaj yeem yog heterozygous lossis homozygous
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog Codominance hauv cov noob caj noob ces tsis yog Mendelian?
Thaum cov alleles rau ib qho kev coj cwj pwm yog codominant, lawv ob leeg qhia sib npaug es tsis yog ib qho tseem ceeb allele noj tag nrho cov kev tswj ntawm ib qho allele recessive. Qhov no txhais tau hais tias thaum lub cev muaj ob qhov sib txawv alleles (piv txwv li, yog heterozygote), nws yuav qhia ob qho tib si tib lub sijhawm
