allele. one of two or more alternative forms of a gene at the same site or locus in each of a pair of chromosomes, which determine alternative characters in inheritance. Called also allelomorph. blank allele. an allele which produces an antigen which cannot be detected. null allele. see silent allele (below).
Polygenic inheritance can be explained as Mendelian inheritance at many loci, resulting in a trait which is normally-distributed. If n is the number of involved loci, then the coefficients of the binomial expansion of (a + b) 2n will give the frequency of distribution of all n allele combinations.
