Easy aaiaoe?: Recessive kāna moʻolelo - ia Aloha ...

Recessive kāna moʻolelo - i kāna moʻolelo i pili i hoike mai ai ia ia iho, ina he mea kekahi Hoʻohaku allele genotype o ka ia hoailona. E aho ike i kēia ho'ākāka 'ana, e ka hana a me ke ala o ka helu kuʻina hoailona ana i ka aaiaoe kiʻekiʻe.

A wahi o ke kumumanaʻo

Kēlā me kēia hiʻona i loko o kānaka ua encoded ma nā nā'ōewe, alleles, kekahi ma kēlā me kēia makua. Alleles i maheleia i loko o Hoʻohaku a me ka recessive. Inā he gamete he mau Hoʻohaku a me ka recessive allele, ka phenotype e hōʻike Hoʻohaku. Keia rula wehewehe i ka mea hoʻohālike o ke kula papa o ka kālaimeaola ina kekahi makua uliuli mau maka, a me ka mea 'ē aʻe - mea eleele, alaila, i ke keiki hoʻoneʻe' ia paha ia eʻeleʻele mau maka, e like me ka uliuli - recessive kāna moʻolelo. Ua triggered kēia rula ina ma ka genotype o ka mea eleele-maka makua elua e like allele Hoʻohaku. E eleele mau maka no ka pane A'ōewe no ka uliuli - i. A laila, i ka wa a ma kela aoao kekahi mau koho:

P: AA m Aa;

F1: Aa Aa Aa Aa.

All heterozygous hua, a me nā mea a pau hoikeia Hoʻohaku - eleele maka.

Apana koho:

P: Aa m Aa;

F1: Aa, Aa, Aa, Aa.

Me keia aoao, a hoike mai ai ia i ka recessive kāna moʻolelo (keia uliuli maka). Ke pahiki i kekahi keiki, e lilo ana he uliuli-maka, - 50%.

Like me ili albinism (pigmentation kāna hana), makapo, hemophilia. Kēia recessive kāna moʻolelo o ka ke kanaka, a hōʻike wale nō i loko o ka wa e kaawale aku o ka Hoʻohaku allele.

Hiʻona recessive kāna moʻolelo

He nui na recessive kāna moʻolelo i kaua kipi i ka hopena o aaiaoe mutations. Hoʻomanaʻo aʻela nō, no ka mea hoike, i ka ike ana o Thomas Morgan me ka hua lele Drosophila. Ka mea maʻamau maka ano no ka makika - ulaula a me kekahi keʻokeʻo-maka nahu kumu ua he mutation ma ka X chromosome. A ua he recessive, ke keka-ua hoʻopili.

Hemophilia A a me ka makapō i no e recessive kāna moʻolelo, ke keka-ua hoʻopili.

E hoomanao i holo recessive kāna moʻolelo no ka laʻana waihoʻoluʻu ka makapō. Ina i kekahi'ōewe kuleana no ka mea maʻamau waihoʻoluʻu pokole, - X, he mutant - X ^d. Crossbreeding Ua like penei:

P: XX X X ^b Y;

F1: XX ^{D, n} XX, XY, XY.

Ia mea, ina o ka makua kāne,ʻo iaʻano makapō, a me kona makuwahine i loko o maikai ola, a pau nā keiki e e ola, akā, na kaikamahine, e lilo ana nā moku halihali mokulele o ke ano makapo'ōewe, i mea he 50% manawa e e hōʻike i loko o kā lākou mau keiki kāne. Women colorblindness ka loa pohihihi keia, no ka mea, ka mea olakino X chromosome compensates no ka mutant.

Other ano o ka'ōewe AaOIeIOUIeXAOAaIN

Ka mua hoʻohālike me ke ano o kona mau maka - i laʻana o ka huina domination, i mea, i ka Hoʻohaku'ōewe ua loa mokuhia mai i ka recessive'ōewe. Hoailona hoike aku i loko o ka genotype hoʻopili like i ka Hoʻohaku allele. Akā, he mau manawa, i ka wa o ka Hoʻohaku'ōewe mea,ʻaʻole loa suppresses ka recessive, a ua hoike mai i ka hua he keʻa - he hou hiʻona (kodominirovanie), a me ka hoike mai ai ia lakou iho nā nā'ōewe (kāpili dominance).

Kodominirovanie - he ke nānā kŰia. Ma kānaka kodominirovanie akaka wale 'āina hoʻoili o ke koko pūʻulu. E kekahi o na makua i ka lua o ka pūʻulu o ke koko (AA), i ka lua - ke kolu o ka pūʻulu (BB). Mai ka A a me B ano Hoʻohaku. I ka wā i kela kapa, ua loaʻa i nā keiki i ke koko ha o ka hui, kivila mai me AB. I mea akaka ma ka phenotype o nā hoailona.

Kekahi ili kala like 'ole o na mea he nui flowering mea kanu. A hiki aku oe i kela kapa o kaʻulaʻula, a keʻokeʻo rhododendron, i ka hopena hiki e nā ulaula, a keʻokeʻo, aʻelua-waihoʻoluʻu pua. ʻOiai ula mea Hoʻohaku, a ma keia hihia, ka mea, aole ia i uhi i ka recessive kāna moʻolelo. Kēia AaOIeIOUIeXAOAaIN ma i nā 'ano maopopo no ia like vigorously genotype.

Kekahi hana laʻana ua pili i ka kodominirovaniem. Ma ka holo ulaula, a keʻokeʻo cosmos i ka hopena i e nonono. Ke a pink kala like 'ole o ka hopena o ke kāpili dominance, i ka wa a ka Hoʻohaku allele hana me ka recessive. Penei, he hou waena hiʻona.

ole-allelic AaOIeIOUIeXAOAaIN

Ua Ua stipulated i ke kanaka genotype kāpili dominance mea,ʻaʻole nona. kāpili dominanceʻano papa hana mea i pili i ka waihoʻoluʻu hooilina. Inā kekahi o na makua o ka ili, ua pouli, ka kekahi malamalama, a me ke keiki - pouli, waena koho, ia mea,ʻaʻole he laʻana o ke kāpili dominance. Ma keia hihia pono hana AaOIeIOUIeXAOAaIN nonallelic nā'ōewe.
