Answer by Flying ninja. Confidence votes 7. The dominant gene will always cover up the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other.There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.nswer by Flying ninja.

1 For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes (although, with two copies you will still have brown eyes). 2  If both alleles are dominant, it is called codominance. These different versions of a gene are called alleles. 2  Alleles can be either dominant or recessive. 3  Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous).
