We consider three independent sex-determining loci and we encode genotypes by triplets i=(i1,i2,i3), where in corresponds to the genotype at locus n. At each locus, the genotypes are unordered, meaning that the heterozygous genotype AB is equivalent to BA. The sexual phenotype determined by...
InMendelian inheritance, the interaction between dominant and recessive alleles produce the organism phenotype, or the collection of observable characteristics. An organism that has two identical alleles is calledhomozygous. Two different alleles, meaning a dominant and a recessive one, produce aheterozygou...
