Qhov xav tau genotype piv thaum ob lub heterozygotes hla yog 1 (homozygous dominant): 2 (heterozygous): 1 (homozygous recessive) . Thaum pom qhov sib piv ntawm phenotypic ntawm 2: 1, tej zaum yuav muaj cov kab mob tuag taus uas tuag tag (tseem hu ua cov noob tuag lossis tuag) yog alleles uas ua rau cov kab mob tuag taus uas nqa lawv. … Lethal alleles tuaj yeem ua rau lub cev tuag ua ntej yug menyuam lossis txhua lub sijhawm tom qab yug menyuam, txawm tias lawv feem ntau tshwm sim thaum ntxov. https://en.wikipedia.org › wiki › Lethal_allele

Yuav ua li cas thaum hla 2 heterozygous?
Yog qhov kev xeem hla ua rau cov xeeb ntxwv tsis zoo, ces niam txiv kab mob yog heterozygous rau cov lus nug. Yog hais tias qhov kev xeem hla tau tsuas yog phenotypically dominant xeeb tub, ces tus niam txiv kab mob yog homozygous dominant rau allele nyob rau hauv nqe lus nug.
Pob ob tus neeg heterozygous tsuas tsim cov xeeb ntxwv heterozygous?
Ib tug hla ntawm ob tus neeg sib txawv ntawm cov neeg yug los yuav tsim heterozygous xeeb tub. … Cov neeg yug los muaj tseeb yog homozygous, muaj ob qho tib si rau cov noob, hos cov neeg heterozygous muaj ob qho sib txawv rau cov noob.
Qhov tshwm sim yog dab tsi uas ob lub heterozygotes hla yuavtsim kom muaj homozygous dominant cov xeeb ntxwv?
7. Yog tias ob homozygous dominants hla, qhov tshwm sim uas ib tug xeeb ntxwv yuav yog homozygous dominant yog 100% lossis 1.00.
Yuav ua li cas yog ob leeg heterozygous?
