Ntau txoj hauv kev, koj yog koj cov proteins - koj lub cev thiab biochemical cov yam ntxwv tau qhia thiab tswj los ntawm cov proteins, uas yog coded los ntawm koj DNA. Cov noob uas tau hais tawm yog lub luag haujlwm rau koj qhov zoo, lossis phenotype. Lub phenotype tseem ceeb yog qhov zoo uas tshwm sim los ntawm cov noob tseem ceeb.
Tus piv txwv tseem ceeb phenotype yog dab tsi?
Muaj ntau tus yam ntxwv ntawm tib neeg phenotype, uas yog tswj los ntawm cov tseem ceeb alleles: Cov plaub hau tsaus yog tseem ceeb tshaj cov plaub hau daj lossis cov plaub hau liab. Cov plaub hau curly yog dominant tshaj cov plaub hau ncaj. Baldness yog qhov tseem ceeb tshaj plaws. Muaj tus poj ntsuam lub ncov (v-puab plaub hau) yog qhov tseem ceeb tshaj qhov muaj plaub hau ncaj.
Koj paub li cas phenotype yog dominant?
txhawm rau txheeb xyuas seb cov kab mob twg uas pom qhov tseem ceeb yog homozygous lossis heterozygous rau ib qho allele, tus kws tshawb fawb tuaj yeem ua ib xeem hla. Cov kab mob nyob rau hauv nqe lus nug yog hla nrog ib tug kab mob uas yog homozygous rau lub recessive zoo, thiab cov xeeb leej xeeb ntxwv ntawm tus ntoo khaub lig xeem yog soj ntsuam.
Tus phenotype twg yog qhov tseem ceeb thiab rov ua dua?
Ib tug tus neeg uas muaj ib qho tseem ceeb thiab ib qho kev rov qab ua rau cov noob yuav muaj cov phenotype tseem ceeb. Lawv feem ntau suav hais tias yog "cov neeg nqa khoom" ntawm cov allele recessive: lub recessive allele nyob ntawd, tab sis qhov recessive phenotype tsis yog.
Yuav ua li cas genotype yog dominant?
Ib qho tseem ceeb allele yog txhais los ntawm tsab ntawv loj (A piv rau a). Txij li thaum txhua tus niam txiv muab ib qho allele, qhov ua tau ua ke yog: AA, Aa, thiab aa. Cov xeeb leej xeeb ntxwv uas nws genotype yog AA lossis Aa yuav muaj qhov tseem ceeb tshaj plaws uas tau hais tawm phenotypically, thaum cov neeg aa qhia txog qhov tsis zoo.
Pom zoo:
Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog tus bestiary hauv dab dab dab?
Wiki Targeted (Kev Ua Si) Beasts yog cov lus hu uas muab Metropolitan Era monsters txhawb nqa rau stats nrog rau cov txiaj ntsig hauv kev sib ntaus sib tua. Tus Bestiary tuaj yeem kho tau ntawm qib 18, qhov twg cov neeg ua si tuaj yeem qhib thiab nce qib Beasts los txhim kho lawv lub zog thiab cov teebmeem.
Nyob rau hauv tsis tiav dominance yog dab tsi phenotype ntawm heterozygotes?
Hauv kev ua tiav tsis tiav, cov phenotype hauv ib tus neeg heterozygous pom qhov tsis tshua muaj siab dua li ntawm ib tus neeg homozygous rau cov tseem ceeb allele, kom AA thiab Aa genotypes tsim cov phenotypes sib txawv. Li no, lub heterozygote (Aa) yuav muaj phenotype nruab nrab ntawm AA thiab aa tus neeg.
Yam dab tsi yog codominant lossis tsis tiav dominant?
Txoj kev tswj hwm tsis tiav yog thaum cov phenotypes ntawm ob niam txiv sib xyaw ua ke los tsim cov phenotype tshiab rau lawv cov xeeb ntxwv. Ib qho piv txwv yog paj dawb thiab paj liab ua paj liab. Codominance yog thaum ob niam txiv phenotypes qhia ua ke hauv cov xeeb ntxwv.
Puas yog cov dab dab dab dab dab dab tau them?
OHL cov neeg ua si tsis tau nyiaj hli, vim lawv tsis raug lees paub tias yog cov neeg ua haujlwm raws li Txoj Cai Kev Ua Haujlwm. Txawm li cas los xij, lawv suav nrog cov txiaj ntsig xws li nyiaj rov qab txhua xyoo, tag nrho cov nqi kawm ntawv them, thiab daim pib pub dawb.
