genotype
heterogenous
Yes, that is correct. Each trait is controlled by genes, and genes exist in different forms called alleles. For any given trait, an individual can have two alleles—one inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
Phenotype
genotype
The expression of a specific trait in an individual (such as hair color) is determined by two factors,one from each parent. These factors are represented with an uppercase letter for a dominantfactor and a lowercase letter for a recessive factor. The combination of these factors determineshow that trait will be expressed in an individual.

The trait that is determined completly by your DNA is your hair color.
Trait
A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
domanant trait
When more than one gene influences that particular trait.
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
