In the reference to genetics what does dominance and recessive mean

dominance is the one that will be seen in a creature, recessive traits will not be seen, but can still be passed on

Explanation:

if both parents pass on the same recessive gene then their child will show that trait, such as two sets of parents, one dark skinned and one light skinned, their children will be dark skinned, but if their children have a child is has a chance of having light skin because they both carry that recessive trait.
