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.
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait.A recessive trait is one that will be expressed only if both parents carry the trait.f A is the â¦ dominant trait and a is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype.
