Codominance: Ho Hlahloba Khopolo le Mehlala Liphatseng tsa Lefutso
Lefatšeng la liphatsa tsa lefutso, lentsoe "codominance" le hlaha e le khopolo ea motheo eo ho leng bohlokoa ho e utloisisa, haholo-holo ha re leka ho utloisisa hore na litšobotsi tse itseng li futsitsoe joang ho tloha molokong o mong ho ea ho o mong. Codominance e fana ka temohisiso e ruileng mabapi le hore na liphatsa tsa lefutso li sebetsa joang le hore na mefuta-futa ea lintho tse phelang e ka hlaha joang ka mokhoa oa lefa la allele.
Khopolo ea Motheo ea ho Laola Bongata
Codominance ke mofuta oa lefa la liphatsa tsa lefutso leo ho lona li-allele tse peli tse fapaneng tsa jini e le 'ngoe li hlahisoang ka ho lekana, 'me ha ho le e 'ngoe ea tsona e busang kapa e tetebetsang holim'a e 'ngoe. Ho fapana le puso e felletseng, moo allele e 'ngoe e patang polelo ea e 'ngoe, ho codominance, li-allele ka bobeli li kenya letsoho ka ho lekana ho phenotype ea sebopuoa.
Ketsahalo ena e etsahala hobane li-allele ka bobeli lia sebetsa 'me e' ngoe le e 'ngoe e hlahisa protheine e khethollang ka mokhoa o makatsang linthong tse phelang tse jereng li-allele ka bobeli. Ka lebaka leo, batho ka bomong ba heterozygous bakeng sa gene ba tla bontša litšobotsi tsa li-allele ka bobeli.
Mehlala ea Codominance ho Liphatsa tsa Lefutso
E 'ngoe ea mehlala e tsebahalang haholo ea codominance ke sistimi ea sehlopha sa mali sa motho sa ABO. Tsamaisong ena, mofuta oa mali o khethoa ke li-allele tse tharo: I^A, I^B, le i. Li-allele tsa I^A le I^B ke tse ngata, ha allele ea i e le e feteletseng.
– Batho ba nang le allele I^A/I^A kapa I^A/i ba tla ba le mofuta wa madi A.
– Batho ba nang le allele I^B/I^B kapa I^B/i ba tla ba le mofuta wa madi wa B.
– Batho ba nang le allele ea I^A/I^B ba tla ba le mofuta oa mali oa AB, moo li-antigen tsa A le B li hlahang holim'a lisele tse khubelu tsa mali, e leng se bontšang ho busa ha lisele tse ling.
– Batho ba nang le allele ea i/i ba tla ba le mofuta oa mali oa O, moo li-antigen tsa A kapa B li sa hlaheng.
Phenotype e hlahang ho codominance ha se kamehla e hlakileng joalo ka tsamaisong ea ABO. Maemong a mang, codominance e ka hlahisa lipaterone kapa matšoao a itseng nthong e phelang. Mohlala, ho Mirabilis jalapa, kapa lipalesa tsa hora ea bone, 'mala oa palesa o khethoa ke li-allele tse peli, ka bobeli li amehang ho thehoeng ha 'mala. Ha li-allele ka bobeli li hlahisoa ka nako e le 'ngoe, sephetho ke palesa e nang le motsoako o ikhethang oa mebala.
Mekhoa ea limolek'hule e ka morao ho Codominance
Boemong ba limolek'hule, codominance e kenyelletsa tlhahiso e le 'ngoe ea lihlahisoa tse fapaneng tsa lefutso, hangata liprotheine kapa li-enzyme, tse ngotsoeng ke allele ka 'ngoe. Ho fapana le puso e bonolo, moo allele e le 'ngoe feela e hlahisoang, ho codominance, lingoloa tsa RNA le liprotheine tse tsoang ho li-allele ka bobeli li teng 'me lia sebetsa ka seleng.
Nka mohlala oa mofuta oa mali oa AB, moo li-antigen tsa A le B ka bobeli li hlahisoang hobane li-enzyme tsa transferase tse hlahisoang ke li-allele tsa I^A le I^B ka bobeli lia sebetsa. Li-enzyme tsena li eketsa limolek'hule tse itseng tsa lik'habohaedreite holim'a lisele tse khubelu tsa mali, e leng se fellang ka boteng ba li-antigen tse peli tse ka bonoang ke 'mele.
Bohlokoa ba ho busa hammoho ho iphetotseng ha lintho le baeloji
Ho busa hammoho ho na le bohlokoa ba bohlokoa moelelong oa ho iphetola ha lintho le baeloji ea baahi. Ka ho nolofalletsa mefuta-futa ea phenotypic ka har'a baahi, ho busa hammoho ho thusa bokhoni ba sebopuoa ho ikamahanya le maemo le ho pholoha liphetoho tsa tikoloho le likhatello tsa khetho.
Ho ya ka pono ya ho iphetola ha dintho, di-allele tse nang le di-codominant di ka bolokwa hara baahi haeba di-phenotype tse pedi tse hlahang di fana ka melemo e fapaneng ya kgetho. Maemong a mang, ho laola ho ka eketsa phapang ya lefutso ka hara baahi, e leng se dumellang diphedi ho arabela ka tsela e makatsang diphephetsong tse fapaneng tsa tikoloho.
Litšebeliso le Litlamorao tsa Codominance
Ho utloisisa ho laola mafu ha ho bohlokoa feela lipatlisisong tsa motheo tsa liphatsa tsa lefutso empa hape ho na le lits'ebetso tse sebetsang masimong a kang bongaka, temo le theknoloji ea baeloji. Bongaka, tlhahlobo ea liphatsa tsa lefutso ea litšobotsi tse laolang mafu e ka thusa ho hlahloba le ho rera kalafo ea maemo a itseng.
Mohlala, tabeng ea mafu a liphatsa tsa lefutso moo ho amehang litšobotsi tse ngata, liteko tsa liphatsa tsa lefutso li ka khetholla mofuta oa liphatsa tsa lefutso tsa motho ka mong le ho bolela esale pele ponahalo e ka bang teng ea phenotypic e lebisang ho etseng liqeto tse loketseng tsa bophelo bo botle.
Temong, codominance e sebediswa mananeong a ho ikatisa dimela ho kopanya dibopeho tse molemo tse tswang ho di-allele tse fapaneng, ho hlahisa mefuta e metjha ya dimela e nang le dibopeho tse lakatsehang tse kang ho hanyetsa mafu, chai e eketsehileng, kapa ho ikamahanya le maemo a lehodimo.
Ho phaella moo, thuto ea codominance e boetse e bohlokoa lefapheng la theknoloji ea baeloji bakeng sa boenjiniere ba liphatsa tsa lefutso le ho latela litšobotsi tse itseng tse ka bapalang karolo tlhahisong ea li-biofuel, meriana le lihlahisoa tse ling tsa baeloji.

Codominance e senola karolo e 'ngoe ea ho rarahana ha mekhoa ea lefutso la liphatsa tsa lefutso, e bonts'ang mofuta o fetohang le o fapaneng oa bophelo. Kutloisiso e tebileng ea hore na codominance e sebetsa joang e ka bula menyetla e mecha masimong a mangata a saense le a sebetsang, ho tloha ho tebiseng kutloisiso ea rona ea mefuta-futa ea lintho tse phelang ho isa ho nts'etsapele litharollo tse ncha tsa liphephetso tsa lefats'e.
