The effect of the c.-20G>A A allele is consistent with a recessive model, and the protective effect against Sp is exerted only when it is present in homozygosis. For the other two SNPs, no differences were observed as allelic and genotypic frequency in the two subgroups of CF patients....
Recessive(隐性):只能在纯合子中表现,不能再杂合子中表现的 Inbreeding(近亲婚配):三代火三代以内有共同祖先的人婚配 Genetic lethal(遗传致死):突变的等位基因或遗传决定的性状不能再现,但繁殖前不一定死Hardy-Weniberg定律:群体中个体的等位基因和基因型的频率世代维持恒定 Genetic drift(遗传漂变):某一等位基因...
se1(sugary enhancer1)是su1的隐性修饰因子(recessive modifier ),se1等位基因已被成功地整合到许多甜玉米品种中并提高了玉米品质,因此在现代甜玉米育种中具有重要的意义。se1与玉米籽粒中的可溶性糖以及水溶性多糖的代谢有关【6】,但是到目前为止,se1在淀粉代谢中的因果关系和分子遗传基础尚不清楚。 近日,美国...

A total of 20 publications, involving 6,782 cases and 7,767 controls, were included in this meta-analysis. Combined analysis revealed a significant association between -889 C/T polymorphism and cancer risk under an allele model (OR =1.12, 95% CI =1.02–1.24, P=0.02), recessive model (OR...
A cross between two short-tailed mice results in offspring in the ratio of 2/3 short-tailed and 1/3 long-tailed. The best explanation for this result is that (两只短尾小鼠杂交,结果后代中短尾小鼠占 2/3,长尾小鼠占 1/3。对这一结果的最... A. there is a recessive lethal ...

However, FSHD families have been reported in which individuals carrying a D4Z4-reduced allele remain asymptomatic. Recently, it has been proposed that the D4Z4-reduced allele is pathogenic only in association with the permissive haplotype, 4APAS. 年份: 2012 ...
The variant TT genotype of TREH rs17748 and the variant TT genotype of PHLDB1 rs498872 decreased GBM risk in the recessive model. We also found that the TREH rs17748 variant C allele showed an increased risk in males in the dominant model. Our results suggest a significant association ...
