There are two different alleles for the number of fingers on the hands: 5 finger allele and 6 finger allele. when both the 5 finger allele and the 6 finger allele are present in the same individual, the individual has 6 fingers on the hands. which allele is dominant?

The 6 fingers allele is dominant

Explanation:

We are told that the the individual is genotypically heterozygous, that is the have both types of the finger allele: the 5 finger allele and the 6 fingers allele however phenotypically, 6 fingers are observed. From this we can conclude that the 6 fingers allele is the one that is dominant because it is the one that is expressed phenotypically.
