Pleitropy ke eng?
Pleiotropy e etsahala ha lefutso le le leng le susumetsa litšobotsi tse peli kapa ho feta tsa phenotypic tse bonahalang li sa amane. Gene e joalo e bontšang lipontšo tse ngata tsa mofuta o itseng oa liphatsa tsa lefutso e bitsoa pleiotropic gene. Phetoho ea liphatsa tsa lefutso ea pleiotropic e ka ba le phello litšoanelehong tse'maloa ka nako e le' ngoe, ka lebaka la liphatsa tsa lefutso tse ngolang sehlahisoa se sebelisoang ke lisele tse ngata kapa liphofu tse fapaneng tse nang le ts'ebetso e tšoanang ea ho fana ka matšoao.  Pleiotropy e ka hlaha ho tsoa mekhoeng e'maloa e fapaneng empa e ka 'na ea kopana, e kang gene pleiotropy, pleiotropy ea nts'etsopele, le pleiotropy e khethiloeng. Pleiotropy ea liphatsa tsa lefutso e etsahala ha sehlahisoa sa liphatsa tsa lefutso se sebelisana le liprotheine tse ling tse ngata kapa se susumetsa liphetoho tse ngata. Pleiotropy ea nts'etsopele e etsahala ha liphetoho liphatseng tsa lefutso li e-na le liphello tse ngata ho phenotype e hlahang. Selectional pleiotropy e etsahala ha phenotype e hlahang e na le litlamorao tse ngata ho tšoanelehang (ho latela lintlha tse kang lilemo le bong).  Mohlala oa pleiotropy ke phenylketonuria, e leng boloetse bo futsitsoeng bo amang tekanyo ea phenylalanine, e leng amino acid e ka fumanoang lijong,'meleng oa motho. Phenylketonuria e etsa hore amino acid ena e eketsehe'meleng, e leng ho ka bang kotsi haholo. Lefu lena le bakoa ke ho se sebetse hantle ha gene e le 'ngoe ho chromosome 12 e laolang enzyme ea phenylalanine hydroxylase, e amang tsamaiso e mengata, e kang tsamaiso ea methapo le ea letlalo.  Ketso ea liphatsa tsa lefutso ea Pleiotropic e ka fokotsa sekhahla sa ho iphetola ha lintho ka mefuta e mengata ha khetho ea tlhaho, khetho ea thobalano kapa khetho ea maiketsetso tšobotsing e le 'ngoe e rata allele e le' ngoe, ha khetho ea litšobotsi tse ling e rata allele e fapaneng. Liphetoho tse ling tsa liphatsa tsa lefutso li kotsi ho' mele. Likamano tsa liphatsa tsa lefutso le likarabo tsa khetho hangata li bontša pleiotropy.
