gene
Allele that needs only ONE copy to be expressed. It "hides" or "covers up" the other allele.
recessive
dominant
heterozygous

In a heterozygous organism, the dominant allele will mask the recessive one. The organism will show the dominant trait.

law of independent assortment
law of codominance
Both dominant traits can be seen in an organism
codominance
incomplete dominance
genotype
heterozygous
Two dominant traits blend/combine to form a new trait
