Quizplus · Accepted Answer

Alleles are indeed found at genetic loci, which are specific positions on chromosomes. Not all alleles are strictly dominant or recessive; some exhibit incomplete dominance, codominance, or other patterns of inheritance. Also, alleles are alternative forms of a gene, not a phenotype, which is the observable characteristic.
