Because there has to be more than one or we would be all the same
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.
Variations of a gene that control a trait are known as alleles. These variations can differ in their DNA sequence, leading to different expressions of a trait. For instance, a gene controlling flower color may have alleles for red, white, or yellow flowers. The combination of alleles inherited from each parent determines the phenotype, or observable characteristics, of the organism.
A trait that is not expressed when another is present is referred to as a recessive trait.
2 different alelles - heterozygous Same alelles - homozygous
A heterozygous has 2 different alleles for a trait.
The two extreme variations in a are trait are favored in disruptive selection.
it can be big or small, large or tiny. itdoesn't matter the size, shape, or color. its still the same as it was.
Multiple alleles can provide many different phenotypes for a trait because each allele can code for a different version of a trait, leading to a wide range of possible combinations and variations in the expression of that trait.

Variations
A Trait Could Show Up In Two Different Forms
A trait that is not expressed when another is present is referred to as a recessive trait.
Different versions of the same gene are called
Different forms of the same trait, known as variations, can include things like eye color (blue, brown, green), hair texture (straight, curly, wavy), and blood type (A, B, AB, O). These variations are a result of genetic differences among individuals.
2 different alelles - heterozygous Same alelles - homozygous
Genes can have different forms, known as alleles, that produce variations in a specific trait. These alleles can be dominant or recessive, determining which form of the trait is expressed in an individual. Additionally, some alleles can be co-dominant or show incomplete dominance, leading to unique phenotypic outcomes.
