Double recessive An organism containing both recessive alleles of a particular gene and thus expressing the recessive fo双隐性：一个生物体包含一对隐性等位基因，则表现为隐性性状。
For example, in genetics, if a heterozygous plant is selfed, the probability of finding the double recessive is 1 in 4, 例如在遗传学上，一个杂合的植物体为自花受精，发现双隐性性状的概率为1/4或25%。
