Humans have two sets of their chromosomes, one from each parent. Two different alleles for a trait are two different versions of a gene, one usually coming from each parent. Alleles are referred to a dominant or recessive. A trait can be homozygous dominant (both the same dominant allele), heterozygous (one dominant and one recessive), or homozygous recessive (both recessive). "Dominant" alleles are named so because when they are paired with a recessive allele, the dominant one is expresses in the organism's phenotype.
2 alleles make up a genotype. One from the mother, one from the father. For example, the genotype for tallness may be TT.
two different alleles for a trait is to have i don't know?
Alleles
Different forms of the same gene are called alleles.The different forms of a gene are called alleles.
The condition called in a case when you have a two different types of alleles is called as Heterozygous and when this is exactly the opposite that is when it has the alleles for the same source we describe such a condition as a Homozygous. This two terms are of most importance when you take the genetics
Heterozygous
heterozygous for that specific gene.
Alleles
hybrid or heterozygous.
The two different molecular forms of a gene are called alleles.

Heterozygous
Is called a heterozygote (hetero- meaning different, and zygote being the sex cell). Heterozygotes have two different alleles of a particular gene, one in each of their sets of chromosomes. As apposed to homozygotes which have two of the same alleles of a gene.
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
