Puas yog haemophilia dominant lossis recessive?
Hemophilia is a sex-linked recessive disorder. Qhov txawv txav ntawm lub luag haujlwm rau hemophilia yog nqa ntawm X chromosome. Txiv neej muaj ib tug X chromosome thiab ib tug Y chromosome.
YPuas yog hemophilia homozygous lossis heterozygous?
Tus kab mob no tau txais txiaj ntsig los ntawm X-txuas rov qab qhov zoo thiab yog li tshwm sim hauv cov txiv neej thiab tsis tshua muaj nyob hauv cov poj niam homozygous. Heterozygous poj niam rau tus kab mob no hu ua tus nqa.

Dab tsi ntawm qhov tshwm sim hauv qab no tau sim ua pov thawj los ntawm meselson thiab stahl?
Kev sim Meselson thiab Stahl yog ib qho kev sim los ua pov thawj tias DNA replication yog semiconservative semiconservative Semiconservative replication piav txog lub mechanism ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb… Cov txheej txheem no paub raws li ib nrab kev saib xyuas rov ua dua vim tias ob daim ntawv theej ntawm thawj DNA molecule raug tsim, txhua daim ntawv khaws cia (replicating) cov ntaub ntawv los ntawm ib nrab ntawm thawj DNA molecule.
