显性上位(dominant epitasis):在上位效应中,起抑制作用的是一个显性基因,孟德尔比率被修饰为12:3:1的现象。应用学科:遗传学(一级学科);经典遗传学(二级学科)。
绿色对白色有三对基因差异,其中绿色基因有显性上位作用,只需一个绿色基因G存在,即可抑制淡黄色与白色性状的表达。
GF vs WF had difference in three genes, and the G gene had epistatic effect, one W was enough to restrain the express of YF and WF.
结果表明,这些指标的上位效应均不显著,均符合加性—显性遗传模型。
The result showed that the epistatic effect in all of those traits were not significant.
