WebFinally, epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same phenotype. In the shepherd’s purse plant ( Capsella bursa-pastoris ), the characteristic of seed shape is controlled by two genes in a dominant epistatic relationship. WebThe recessive trait will only be expressed by offspring that have two copies of this allele ( Figure ), and these offspring will breed true when self-crossed. Since Mendel’s experiments with pea plants, researchers have found that the …
