Based on dna and polypeptide sequences alone, determine which allele is dominant and which is recessive?

It is not possible to determine the dominance or recessivity of DNA/protein sequences without prior phenotypic data. This means that it is imperative to obtain phenotypic information to be associated with a given molecular sequence.

Explanation:

Dominant and recessive are two different phenotypic variants of the same trait which may be associated with different forms at the gene level (alleles). In a diploid organism, the trait that is observed in the heterozygous organism is called dominant; while the trait that is masked is named recessive. In consequence, the only way to determine the effects of one gene (or its encoded protein) is by observing the phenotype expressed from this sequence.
