al?lele (?-l?l") n. One member of a pair or series of genes

ALLELOMORPH.] --al?le"lic (?-l?"l'k, ?-l?l"'k) adj.

Where is this specific position on a specific chromosome ?

Depends on which 'gene' you are talking about and which organism.
Every 'gene' has a specific location on a chromosome. That is what
geneticists call a 'gene locus'.

This is
what noshell referred to - show us the gene and point to us the exact
position of this "allele" thingy.

Take any gene and show where on this gene is the allele thing.

The allele is a particular form of a particular gene.
