Full Answer

Mendel observed that while only the dominant trait showed in the second generation offspring, the invisible, or recessive trait, reappeared in the third generation. However, Mendel only observed one type of dominance, now called complete dominance. There are several other kinds of dominance, including incomplete dominance, codominance and pseudodominance.

Other phenomena also impact gene expression. These factors include variable penetrance, variable expressivity, and epistasis.
