In genetics ,allele means a gene pair having contrasting character or alternate form . does it mean that heterogygous gene pair are only allelic pair ..then what about homogygous gene pair. .isnt it a alleic pair .
 
Well, actually it means one of the members of that pair in a haploid, diploid, tetraploid or polyploid set: allele 1, 2, 3, 4 and so on. A homozygous pair is indeed an allelic pair - it doesn't matter if the locus is homozygous or heterozygous at the locus in question. Actually, it wouldn't even matter if the locus were fixed, since fixation varies from population to population. Anyway, the point is that 'allele' is about the unit (the single allele) rather than the pair.
