异源四倍体 meaning in Chinese
allotetraploid
allotrtraploid
Examples
- The hatching rate of the gynogens with the cold shock was higher than that of the untreated gynogens . all the gyngens with and without cold shock were examined to be diploid females with 100 chromosomes , providing the evidence that the females of the tetraploid population are homogamety ( xxx )
冷休克处理和未冷休克处理的雌核发育鱼均是二倍体( 2n = 100 )的雌鱼，这证明了异源四倍体螂鲤是雌性的性别决定类型属于xxxx类型。 - In nature conditions , without the injection of the extraneous hormone , the females and males of f _ 9 - f _ 12 could mate each other to produce new next generation of tetraploids . with the stable genetic tetraploidy and the fertility in the nature environments , this allotetraploid population possessed the key factors to form a new species with 200 chromosomes
F _ 9 ? f _ ( 12 )染色体数目的稳定性和正常的性腺结构以及自然条件下的生殖传代行为，说明该异源四倍体鲫鲤已成为一个染色体数目为4n = 200 、遗传性状稳定的新型四倍体鱼群体，具备形成一个新的种群所需的关键因素。 - In some cases the observed segregation ratios even allowed us to clearly determine that m . xiaojinesis is a autotetraploid plants , at least is a isosyndetic allotetraploid . these were the cases of 32 m . xiaojinesis - specific markers and 50 markers present in both parents , which fit 5 : 1 and 11 : 1 ratio respectively . since these cases happened were owing to m . xiaojinesis ' s duplex loci
50个双亲共有标记和32个小金海棠特有标记分别适合11 ： 1和5 ： 1的分离系数，由这两个系数可以推测，小金海棠可能是同源四倍体，至少是同源异源四倍体，因这两个系数都表明其产生是源于小金海棠的双式位点。 - 2 . the gynogenesis of allotetraploid hybrids without the treatment to double the chromosome number , the diploid eggs produced by the females of tetraploid hybrids of red crucian carpx common carp were able to develop to living diploid fish after subjecting to activation of the uv - irradiated sperm
人工诱导异源四倍体鲫鲤的雌核发育异源四倍体鲫鲤能产生二倍体卵子，用uv处理镜鲤的精子，不进行染色体的加倍处理，能获得二倍体雌核发育鱼，通过冷休克对“受精卵”进行处理，仍然获得了二倍体雌核发育鱼。 - The space distribution of pigment gland density on eleven places was analyzed by allotetraploid of ( g . arboreum g . bickii ) and varieties with pigment gland of g . hirsutum g . barbadense and the progeny population which is crossed by allotetraploid of ( g . arboreum g . bickii ) g . hirsutum and ( g . arboreum g . bickii ) g . barbadense
摘要利用（亚洲棉比克氏棉）异源四倍体和陆地棉、海岛棉有色素腺体品种以及由（亚洲棉比克氏棉）异源四倍体为母本，以陆地棉和海岛棉有色素腺体品种为父本，组配成的杂交后代群体，对植株上十一个部位色素腺体密度在群体内的分布进行了初步分析。
