You have 2 alleles for each trait you may have. One is on the chromosome from you mother, the other is on the other chromosome from your father. You have 2 of each of our 23 chromosomes (one from mom, one from dad). This is why you look a little or a lot like your parents.
A gene for any given trait will have loci on both of the
homologous chromosomes
, so there are only two options for the
alleles
(although these can be alike, or homozygous, or different, heterozygous). It doesn't matter how many alleles exist for that gene, there are only two "spaces" where it can exist.
Alleles
Different versions of the same gene are called
A heterozygous organism has two different alleles for a given gene. The opposite of a heterozygous organism is a homozygous organism which has two alleles that are the same for that specific gene. Genes can exist in more than one form and the different forms are called alleles. Alleles code for different types of the same characteristic
The entire genetic identity of an individual including alleles or gene forms that do not show as outward characteristics.
The different molecular versions of the same gene are called alleles.

Alleles
Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
True
The chromosomes in a pair carry the same genes in the same places. There are different versions of the same gene. These different versions of the same gene are called alleles.
heterozygous for that specific gene.
multiple alleles
An allele of a gene resides on a chromosome; as there are typically two chromosomal copies in an individual Cell, there are typically two alleles of each and every gene in the individuals genome, or its genetic complement.
We call a gene that has two different alleles heterozygous.
