What condition involves neither of two alleles of a gene being dominant or recessive, with both traits being equally expressed?

What type of gene interaction involves one gene altering the phenotypic effects of another gene that is independently inherited?

What pattern of inheritance involves two alleles, neither dominant nor recessive, resulting in offspring with a phenotype blending parental traits?
