2.2 Numbered Alleles
Numbering alleles is the simplest way to code
codominant marker
data. A homozygote is indicated by repeating the allele number;
thus 1 2 indicates that the alleles are 1 and 2
(a heterozygotea)
while 1 1 indicates the alleles are 1 and 1
(a homozygote). An
unknown genotype is coded as 0 0. For sex-linked loci, males
have a single allele. With the allele 1, for example, the
phenotype can be coded 1 0 or 1 1.
