An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. Different chromosomes contain different numbers of genes on them, and different organisms contain different numbers of chromosomes.
But for any specific gene on a specific individual organism, it will have only two alleles for each gene: one from its mother and one from its father.
Nobody knows yet exactly how many genes there are on any human chromosome.
Here are some recent figures:
X chromosome 1529 genes (155 million base pairs)
Y chromosome 344 genes (57 million base pairs).
However, these should be regarded as approximate while scientists work towards higher resolution sequencing and more complete interpretation.
Alleles are variations of a trait and there is no set number of alleles in general, however on a chromosome pairs you get one version from mon and another from dad so--- two as long as it is not a multiple allele trait.

alleles that everyone has
The human ABO blood group system is a good example of multiple alleles. There are three alleles involved: IA, IB and IO. If a person inherits two IA alleles, or IA and IO, they will be group A. If they inherit two IB alleles, or IB and IO, they will be group B. If you inherit two IO alleles you will be group O.
codominance and multiple alleles
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

i dont know- but there are 23 pairs of alleles (including the xx or xy ones)
alleles that everyone has
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
It is based on multiple alleles.
There are many tests for alleles that cause human genetic disorders. These tests are usually taken by blood or other bodily samples.
Human blood type is determined by codominant alleles.
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
The heredity of the ABO blood groups are governed by multiple alleles.
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
A multi-allele trait is one that is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
the minimum requirement is one pair but it could be more than one pair, an example can be found in human ABO blood groups. it an example of multiple alleles
There is not enough information to answer this questions. 10 alleles in 1 loci? 10 alleles total? 10 alleles for that gene in the population?
