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.
Those are called polygenic genes! An example is eye colour
Three or more forms of a gene that code for a single trait are called
multiple allele multiple allele
allele
trait
having the some alleles in a single trait.
dominant and others may be recessive.
Alleles
yes its called pleiotropy

an Allele.
Alleles are the different forms that a gene may have for a certain trait. They used to be called allelomorphs.
dominant and others may be recessive.
Alleles
Alleles
its called a hybrid
Alleles are forms of genes for a trait.
Alternate forms of a gene are called alleles.
