Dominant and recessive traits in humans. 1  1. ï¨ There are over 200 traits that are transmitted from generation to generation in humans. These interesting aspects of human genetics are known as hereditary traits. 2  2. There are two or more variations in most ofthe genes called alleles.
The words dominant and recessive are encountered in the study of biology, particularly physical traits in the study of genetics. For every physical trait, you receive two copies of the gene, one from your father, and the other from your mother.ecessive genes are showed up only when the organism receives recessive copies from both parents (aa).
