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.
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.
ok there is a such thing called a punnet square you can label them by putting the trait in one of those
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
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.
A trait that is not expressed when another is present is referred to as a recessive trait.
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.
