Genes. are not recessive or dominant.. Alleles. of genes are not recessive or dominant.. The . proteins made by alleles of genes . are not recessive or dominant.. You cannot tell if a trait is recessive or dominant based on the genes that affect it or the alleles in a population.. What are the Dominant and Recessive Traits in Humans?. 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. These are some of the common dominant and recessive traits in humans that can be easily observed in people around you. . You . have two genes for them. One inherited from your father and one from your mother. The way that a physical trait is expressed, and hence the way you look is a result of either a combination of dominant genes, a dominant and a recessive gene or two recessive genes..

The . dominant impression. of a piece of writing is the mood, feeling, atmosphere or quality that is the focus of the text. A strong text allows readers to “feel” the mood of the writer.
