Meaning of dominant gene in science. The main difference between dominant and recessive genes is that the dominant genes always express the dominant trait whereas the recessive genes express the recessive trait. A dominant trait is an inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele traits also known as phenotypes may include features such as eye color hair color immunity or susceptibility to certain diseases and facial features such as dimples and freckles.
