The strongest evidence for linkage in 147 families with late-onset PD was on chromosome 17 near the tau gene -- previously shown to be involved in other neurodegenerative diseases including frontotemporal dementia with parkinsonism and progressive supranuclear palsy.

147个患有迟发型帕金森氏症的家庭在遗传研究中被发现，该病与17号染色体上的tau基因有关联。以前tau基因被认为与其它的神经变性疾病有关，如伴有震颤麻痹的额颞型痴呆以及进行性核上性麻痹有关。

More directly, their offspring could hae a lower ploidy because of potential links between somatic and gametic chromosome loss.

尤其体细胞染色体丢失和配子染色体丢失的潜在联系，可能会更直接地导致后代基因组低倍化。

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。

The data obtained indicated the presence of putative tumor suppressor geneat chromosome 1p and was valuable for fine mapping,cloning or candidate identification o...

为抑癌基因的精确定位、克隆或鉴定提供了有价值的参考资料。

GISH using genomic DNA of each pines as probe revealed full chromosome paining on each other's genome.

利用油松和云南松总DNA作为探针，对高山松的染色体组进行双探针基因组原位杂交。

To reveal the construct of hybrids, GISH showed there was no chromosome of ryegrass.

为了了解细胞内染色体构成，GISH显示未发现黑麦草染色体的存在。

The data byχ~2 were consistent with the separation ratio as 1: 2: 1 χ~2=4.028＜χ_(0.05,2~2=5.99, which further conformed that glandless character was controlled by a incomplete dominance gene, Gl_2~e. 2. SSR markers every about 5cM were selected in the chromosome 12 of our lab genetic linkage map to screen the parent plants. The markers with the polymorphism were used to amplify the DNA of 210 F_2 segregating plants selected randomly and recorded the marker genotypes. After eliminating the segregation distortion markers byχ~2 test, other SSR markers were detected by linkage analysis.

二、参照本实验室海陆种间遗传连锁图谱第12染色体上的SSR标记，平均每5cM左右选择一个标记进行亲本多态性的筛选，筛选出具有多态性的标记位点进一步扩增随机抽取的210个F_2群体单株的DNA，鉴定每个个体的标记基因型。X~2检测剔除偏分离标记后进行连锁分析，发现Gl_2~e基因位于CIR362与NAU5079之间，进一步参考图谱上位于CIR362与NAU5079之间的标记加密图谱，最终将其定位在CIR362和NAU2251b、NAU3860b、STV033之间。

However, if a Y-chromosome is present , it stimulates the undifferentiated gonadal cell mass to develop into testicles .

然而，如果受精卵中存在Y染色体，它会调控未分化的生殖细胞团发育成睾丸。

Fromthese facts,It could be deduced that 8 to 14 pairs of chromosomes possessed a certaindegree of hetorology,which was directly groved to be hybrid origin of P.tomentosaaccording to the good chromosome homology and fertility of P.bolleana and thehybrids of P.tomentosa×P.bolleana,it could be further deduced that the original parentsof P.tomentosa involved probably P.bolleana or P.alba.

从终变期、中期I的染色体构型看，有数目不等的联会程度较差的单价体和棒状二价体出现，在后期I，甚至末期I亦可见到含落后染色体分裂相的细胞，由此推断可能有8~14对染色体表现出一定程度的异源性，鉴于新疆杨以及毛白杨与新疆杨杂交产生的杂种毛新杨的染色体同源性较强、育性较好等现象，进一步推断毛白杨起源亲本可能包括新疆杨或银白杨。

We got alerted a couple of times while we were down south that HETs were on the way to bring us back up north because things were going to go hot again, but it was just rumors.

南下的途中我们不只一次得到警告说重型装备运输车将拉着我们重新北上，因为局势正在变得重新紧张起来，但这只是谣传。

It's the one where they find the ghost in the salt mine.
