Recessive traits are inherited genetic traits that you only see when both parents possess the gene. If one parent has the recessive trait and the other has the opposing dominate trait, you’ll see the dominate trait in their children. Of course, if both parents have the dominate trait, you’ll also see that trait in their children. Some recessive traits or characteristics occur more commonly than others. Some recessive traits occur more often than the corresponding dominant traits, if the dominant gene is rare in a population.

Fingers and Toes
Common recessive traits include having the normal number of fingers and toes, fingers and toes of normal length and normal joints. Dominant traits include extra fingers or toes, abnormally short fingers or toes, missing joints and double jointed fingers or toes. These recessive traits occur much more frequently than these dominant traits, of course.
Type O blood, the most common blood type in humans, is a recessive trait. Types A blood, B blood and AB blood are all dominant traits and occur less often.
A sensitivity or susceptibility to poison ivy is a common recessive trait. An immunity to poison ivy, on the other hand, is a dominant trait that occurs much less often.
