Question

how many allele that antigen I have​

Answer 1

Answer:

German Allel and Greek ἄλλος állos, "other")[1][2][3] is a variant form of a given gene,[4] meaning it is one of two or more versions of a known mutation at the same place on a chromosome. It can also refer to different sequence variations for a several-hundred base-pair or more region of the genome that codes for a protein. Alleles can come in different extremes of size. At the lowest possible end one can be the single base choice of a single nucleotide polymorphism (SNP).[5] At the higher end, it can be the sequence variations for the regions of the genome that code for the same protein which can be up to several thousand base-pairs long.[6][7]
