The results showed:① The new gemplasms had high nutritive value and taste quality and were similar as the protogene type in each biochemical constitution.② The heterotic rates were negative orientation on the most of quality character,but it was evidently different from the growth vigour character.③ The external...

dominant character:显性性状
孟德尔把F1表现出来的亲本性状叫做显性性状(dominant character),而F1中没有表现出来的亲本性状叫做隐性性状(recessive character)F1自交. 在子二代群体中,亲本的相对性状又分别表现出来,

pedigree analysis:家系分析
人的突变的检出在人中,上述方法自然不能用,所以突变的检出得依靠家系分析(pedigree analysis)和出生调查. 一般地说,常染色体隐性突变难以检出,因为一个隐性性状的出现,很可能是由于两个杂合个体的婚配,而不是由于隐性突变的缘故. 相反的,
