Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov tsis sib xws yog tias, nyob rau hauv assortative mating, mating tshwm sim ntawm phenotypically zoo li kab mob thaum nyob rau hauv disassortative mating, mating tshwm sim ntawm ob kab mob uas phenotypically txawv.
Nyob rau hauv cov noob caj noob ces, mating yog qhov tshwm sim tseem ceeb rau kev ciaj sia ntawm ib hom tsiaj. Qhov tshwm sim ntawm mating yog txiav txim siab ntawm Hardy Weinberg kab zauv. Txawm li cas los xij, assortative mating ua raws li Hardy Weinberg equilibrium, thaum disassortative mating tsis ua raws li qhov sib npaug.
Assortative Mating yog dab tsi?
Assortative mating yog ib hom mating qhov twg khub niam txiv zoo sib xws hauv lawv cov phenotypes. Qhov tshwm sim no tseem hu ua qhov zoo assortative mating lossis homogamy. Yog li ntawd, hom mating no tsis yog hom kev sib tw random. Thaum lub sij hawm assortative mating, cov kab mob uas zoo sib xws phenotypes nyob rau hauv cov xim, pigmentation thiab lub cev loj mates nrog ib leeg. Tsis tas li ntawd, qhov tshwm sim ntawm assortative mating kuj nce nrog genetic compatibility. Tsis tas li ntawd, lub tswv yim no belongs rau pej xeem noob caj noob ces nyob rau hauv lub teb ntawm noob caj noob ces.
Daim duab 01: Assortative Mating
Muaj ntau qhov kev xav uas piav qhia qhov tshwm sim ntawm kev sib koom ua ke. Intrasexual kev sib tw yog ib qho tseem ceeb ntawm kev sib koom ua ke; Piv txwv li, muaj peev xwm muaj ob peb txiv neej sib tw rau tus poj niam loj. Tsis tas li ntawd, kev sib tw hauv zej zog kuj tuaj yeem ua rau muaj kev sib koom ua ke. Qhov no yuav ua rau cov kab mob sib txawv uas muaj cov yam ntxwv zoo sib xws los ua phooj ywg ntawm ib leeg. Cov xwm txheej sib tw yuav, yog li ntawd, ua rau muaj kev sib koom ua ke los ntawm qhov sib thooj es tsis yog xaiv.
Dab tsi yog kev sib deev tsis sib haum?
Disassortative mating tseem hu ua qhov tsis zoo assortative mating lossis heterogamy. Qhov kev sib tw no ua rau muaj kev sib tw ntawm ob lub cev nrog qhov sib txawv ntawm lawv cov phenotypes. Yog li, qhov sib txawv ntawm caj ces kuj tseem siab ntawm ob lub cev. Txawm li cas los xij, txoj kev mating no tsis tshua muaj ntau tshaj qhov zoo mating lossis assortative mating. Raws li cov noob caj noob ces, txoj kev no ntawm mating deviates los ntawm lub hauv paus ntsiab lus Hardy Weinberg.
Tsis tas li ntawd, txoj kev sib tw no txo qis kev sib tw ntawm cov kab mob. Txawm li cas los xij, muaj tsawg lub sijhawm rau hom mating no tshwm sim. Daim ntawv no ntawm mating yog ntau random thiab tsis tau txiav txim siab ua ntej. Cov kab mob uas raug kev sib deev tsis sib haum xeeb yuav muaj qhov sib txawv ntawm lawv cov xim, pigmentation thiab lawv lub cev loj.
Dab tsi yog qhov zoo sib xws ntawm Assortative thiab Disassortative Mating?
- Ob hom mating yuav ua rau cov xeeb ntxwv.
- Lawv tuaj yeem tshwm sim; Txawm li cas los xij assortative mating muaj tus nqi qis ntawm qhov tshwm sim random.
Qhov txawv ntawm Assortative thiab Disassortative Mating yog dab tsi?
Qhov sib txawv tseem ceeb ntawm kev sib koom ua ke thiab kev sib koom ua ke yog nyob ntawm qhov phenotype zoo sib xws ntawm cov kab mob hauv kev sib raug zoo mating. Yog li, nyob rau hauv ib qho kev sib raug zoo, cov kab mob koom nrog hauv mating muaj siab phenotypic zoo sib xws thaum nyob rau hauv ib tug disassortative kev sib raug zoo, cov kab mob koom nyob rau hauv mating muaj ib tug tsawg phenotypic zoo sib xws. Tsis tas li ntawd, Hardy Weinberg kab zauv yog txaus siab nyob rau hauv ib tug assortative mating qauv thaum nws tsis txaus siab nyob rau hauv ib tug disassortative mating qauv.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab tsis sib xws.
Summary – Assortative vs Disassortative Mating
Assortative mating thiab disassortative mating yog ob qhov tshwm sim uas ua rau muaj kev sib txuam ntawm cov kab mob hauv ib hom. Assortative mating tshwm sim los ntawm mating ntawm ob kab mob uas qhia cov phenotypes zoo sib xws. Txawm li cas los xij, kev sib tw tsis sib haum xeeb tshwm sim los ntawm kev sib koom ua ke ntawm ob lub cev uas qhia qhov sib txawv ntawm cov phenotypes. Vim qhov sib txawv no, lawv kuj coj txawv txawv ntawm txoj kev uas lawv ua raws li Hardy Weinberg equilibrium. Muaj ntau random mating tshwm sim nyob rau hauv disassortative mating thiab tsawg randomness nyob rau hauv assortative mating. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm assortative thiab disassortative mating.
