Well every gene in the human genome codes for something different. The fact that variety exists is determined by the alleles of that gene. The human genome has over 35,000 genes that all work together to form a persons genotype. Observable features are an organisms phenotype and those are composed of different traits, i.e. eye color, hair color, certain behaviors. All of these are also coded for by specific genes.
No organism can have just 2 traits and all traits are by definition for different things. Even the simplest organisms have several hundred different traits.
Perhaps you have confused the terms "alleles for a trait" and "traits".
If you meant "an organism with 2 different alleles for a trait" the answer is "heterozygous".
Variation
variations
A heterozygous has 2 different alleles for a trait.
A trait that is not expressed when another is present is referred to as a recessive trait.
a phenotype is the physical characteristics of an organism based on its genotype.
epistasis
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 allelesβone inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.
A heterozygous has 2 different alleles for a trait.
An organism with two like alleles for a trait is homozygous for that trait.
What is heterozygous? Your inherited characteristics are determined by your genes. Zygosity refers to the similarity of genes for a trait in an organism. If both genes are different, the organism is heterozygous (hetero = different) for that trait. If both genes are the same, the organism is homozyous (homo = same).
Heterozygous.
what do we call factors that control traits

A trait that is not expressed when another is present is referred to as a recessive trait.
Alleles are forms of genes for a trait.
genes and the environment
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.
