When the horizontal level falls down the slope-break,a full horizontal level fluctuating cycle is formed,a system including lowstand tract,lake expand and lake shrink(trisection tracts).
当水平面下降到坡折带以下时,构成一个完整的水平面升降旋回,可形成包括低水位、湖扩展、湖萎缩3个体系域的层序(三分体系域);当水平面未下降到坡折带以下时,构成一个不完整的水平面升降旋回,可形成包括湖扩展、湖萎缩2个体系域的层序(二分体系域)。
) male_sterile line 1066A as female parent and Yugu 1 primary trisomic series (1-7) and tetrasomics 8, 9 as male parents, chromosome location of gene for male_sterility and yellow seedling in line 1066A was studied by primary trisomic analysis.
)雄性不育系 10 6 6A为母本 ,豫谷 1号三体 (1～ 7)及四体 8和四体 9作父本进行杂交 ,应用初级三体分析法 ,进行了谷子雄性不育基因和黄苗基因的染色体定位研究。
On the basis of G-banding, the proband showed a translocation between chromosomes of 9p and 21q and partial 9p trisomy.
3)pat,是部分9p三体。
