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.
For example, if a person has one gene for blue eyes and one for brown, that person will always have brown eyes because they are the dominant trait. For a person to have blue eyes, both their genes must be blue (recessive). When a person has two dominant alleles, they are referred to as homozygous dominant.If they have one dominant allele and one recessive allele, they are referred to as heterozygous. A dominant trait when written in a genotype is always written before the recessive gene in a heterozygous pair.A heterozygous genotype is written Aa, not aA.est 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.
