Iraruakē me kaiao iraruarite

Ko tētahi o nga āhuatanga tino nui o tetahi kaiao ora ko whakapapa, ki ngā whanaketanga whāriki o te paraneta, me te te tiaki o te momo kanorau i runga taua mea. Ko te kōwae iti o te whakapapa mahi ira - āhuatanga hanganga o te rāpoi ngota pītauira, kawenga hoki te whakawhiti o te mōhiohio ā-ira e pā ana ki te āhuatanga ngā o te tinana. Tei runga i te tohu o tohaina tino me ira ngoikore. He āhuatanga āhuatanga o ngā waeine tino ko te kaha ki te "pehi" ngoikore, te whakarato i te mana i runga i te rauropi, e kore tuku ki a ratou kia whakakitea i roto i te whakatupuranga tuatahi. Heoi, kia tuhia te reira e me ki te mana tonu i kitea ai oti, i roto i nei te ira ngoi kore taea ki te rawa pehi faaiteraa o superdominance ngoikore, me te whakarato mō te whakaatu o ōrite ngā āhuatanga i roto i te puka kaha atu i roto i kaiao iraruarite. I runga anō i te aha te huru o te allelic (arā, te kawenga mō te whanaketanga o te tohu taua) ira e tango i te reira i te momo matua, tu iraruakē me kaiao iraruarite.

Whakamāramatanga o te kaiao iraruarite

kaiao iraruarite - he taonga o kararehe, me e rua o te taua (tino ngoikore ranei) ira i runga i te pūtake ngā. He āhuatanga motuhake o te whakatupuranga i muri o te mau taata iraruarite ko te kore o te Pharoah o pūāhua me ratou taeoliia. Ko te nuinga te take e kei te tohuira iraruarite o te kaiao kotahi anake te momo o tohuhema, whakaritea e te pukapuka whakapaipai i roto i te take ko reira he huaira ngoi, a whakapae ka lave ngoikore. rerekē kaiao iraruakē i roto i taua i roto i ratou irarā rerekē, me, runga i, i whai ahua ai momo rerekē e rua o tohuhema. Ka taea te denoted kaiao iraruarite i nui ngā irarā ngoikore rite aa, BB, aabb, me ētahi atu Fakatatau ki ai, kaiao iraruarite ngā irarā ngoi, i te AA waehere, BB, AABB.

tauira o te tupu

Whiti e rua kaiao tohuira iraruakē e kia conventionally whakaritea ai rite Aa (ai A - tino, a - te ira ngoikore), whakarato reira te taea o te whiwhi i te tūponotanga rite ngā rerekē e whā o tohuhema (kē tohuira) i te nakunaku ki 3: 1 tohuāhua. I raro i tohuira i roto i tenei take te tikanga he raupapa o ira e roto i te huinga diploid o te pūtau ngā; he tohuāhua - he pūnaha o ngā āhuatanga o waho, me te ā o te rauropi i roto i te pātai.

ripeka Dihybrid me ona āhuatanga

A feruri i te ture hono ki te tukanga kahui, i whai wāhi ngā rauropi iraruarite. I roto i te take taua, ki te mea i reira te mea he rua-ranu poligibridnoe ranei whakawhitinga, ahakoa o te natura mau huru heritable, puta wāhinga i te ōwehenga o 3: 1, a he tika hoki tetahi rahinga tenei ture. Hybridization o nga mau taata tuarua-whakatupuranga i roto i tenei take hanga nga momo matua e wha o tohuāhua i roto i te ōwehenga 9: 3: 3: 1. E tano ia tapao e he tika mo te huirua o ngā pūira takirua tenei ture taunekeneke o ira e kore e i kawea i roto i roto.
