Investigating the Results of Inherited Traits
... When one gene in a gene pair is stronger than the other gene, the trait of the second gene is masked or hidden. The stronger gene is the dominant gene. The gene that is masked is the recessive gene. Dominant genes are written as capital letters and recessive genes are written as lower case letters. ...
