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.
A purine is a heterocyclic aromatic organic compound. It consists of a pyrimidine ring fused to an imidazole ring. Purines, which include substituted purines and their tautomers, are the most widely occurring nitrogen-containing heterocycle in nature.his is called complementary base pairing. In RNA, the complement of adenine is uracil instead of thymine. Other notable purines are hypoxanthine (4), xanthine (5), theobromine (6), caffeine (7), uric acid (8) and isoguanine (9).
