Best Answer: Dominant trait refers to a genetic feature that hides the recessive trait in the phenotype of an individual. A dominant trait causes the phenotype that is seen in a heterozygous (Aa) genotype. Many traits are determined by pairs of complementary genes, each inherited from a single parent.est Answer: Dominant trait refers to a genetic feature that hides the recessive trait in the phenotype of an individual.

A white, crystalline compound, C5H4N4, from which is derived a group of compounds including uric acid, xanthine, and caffeine. Or a purine derivative, especially the bases ad â¦ enine and guanine, which are fundamental constituents of nucleic acids.
Guanine is the other purine nucleotide in DNA. Guanine pairs with cytosine in the DNA structure. Guanine differs from adenine in that it is made up of oxygen in addition to carbon, hydrogen and nitrogen. Like adenine, guanine consists of two rings, one with five members and one with six. Guanine also allows for synthesis of glucose when it is the nitrogenous base for guanosine triphosphate.
