A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.

What is it called when three or more contrasting genes control a trait?
When three or more contrasting genes control a trait, it is called polygenic inheritance. This type of inheritance involves multiple genes interacting to influence a single trait, resulting in a continuous distribution of phenotypes in a population.
What are the different forms of characteristics called?
trait
When two or more forms of the gene for a single trait exist some forms may be?
When two or more forms of a gene for a single trait exist, some forms may be dominant and others recessive. Dominant forms of a gene will be expressed over recessive forms in the phenotype. This is known as codominance or incomplete dominance.
The different forms of a trait that a gene may have are called?
Alleles
Can multiple genes control a single trait?
yes its called pleiotropy
There or more forms of a gene that code for a single trait are called?
phenotype

What are the different formes of genes called?
Alleles are forms of genes for a trait.
What are the alternative genes for a trait?
Alternate forms of a gene are called alleles.
