Hauv biology , lub sij hawm phenotype ” txhais tau tias yog cov yam ntxwv pom tau thiab ntsuas tau ntawm lub cev los ntawm kev sib cuam tshuam ntawm cov noob ntawm cov kab mob, ib puag ncig, thiab kev hloov pauv tsis sib xws. Daim duab no (Punnett square) qhia txog kev sib raug zoo ntawm phenotype thiab genotype.

Ua li no, dab tsi yog phenotype hauv biology piv txwv?

noob caj noob ces. Phenotype , tag nrho cov yam ntxwv pom tau ntawm cov kab mob uas tshwm sim los ntawm kev sib cuam tshuam ntawm nws cov genotype (tag nrho cov noob caj noob ces) nrog ib puag ncig. Piv txwv ntawm observable yam ntxwv muaj xws li tus cwj pwm, biochemical zog, xim, puab, thiab loj.

Ib tug kuj yuav nug, dab tsi yog qhov yooj yim txhais ntawm phenotype? npe. Phenotype yog txhais raws li cov yam ntxwv ntawm lub cev thiab lub siab lub ntsws ntawm ib lub cev los ntawm ob qho tib si noob caj noob ces thiab ib puag ncig, los yog ib pawg ntawm cov kab mob muaj xws li cov yam ntxwv. Ib qho piv txwv ntawm phenotype yog ib pawg ntawm cov kab mob uas txhua tus cuam tshuam rau tib txoj hauv kev los ntawm xwm thiab kev txhawb nqa.

Tsis tas li ntawd, dab tsi yog qhov piv txwv ntawm phenotype?

A phenotype yog ib qho zoo uas peb tuaj yeem soj ntsuam. Cov noob muaj cov lus qhia, thiab qhov tshwm sim ntawm peb lub cev ua raws li cov lus qhia no (rau piv txwv , ua pigment nyob rau hauv peb ob lub qhov muag), yog a phenotype qhov zoo, zoo li qhov muag xim. Qee lub sij hawm qhov zoo yog qhov tshwm sim ntawm ntau cov noob sib txawv, zoo li 16 cov noob muaj lub luag haujlwm rau qhov muag xim.

Dab tsi yog genotype thiab phenotype hauv biology?

Genotype thiab phenotype yog ob lub ntsiab lus tseem ceeb hauv kev tshawb fawb ntawm noob caj noob ces. Lub cev genotype yog cov txheej txheem ntawm cov noob hauv nws DNA lub luag haujlwm rau ib qho kev zoo. Lub cev phenotype yog lub cev qhia ntawm cov noob no.
