Traits such as hair color, freckles, and certain diseases can be passed from generation to generation. You recieve one copy of a gene from your biological mother, and one copy of a gene from your biological father. alternative forms of a gene are called alleles. The genes inheited can form either dominant or recessive phenotypes. The dominant phenotype is defined as the phenotype that results from the heterozygous gneotype. It is 2/3 likely that you will have the dominant phenotype, and 1/3 likely you will have the recessive phenotype. The dominant phenotype is not stronger or better than the recessive, it is more likely because it is haplosufficient: one copy of the dominant allele is sufficient for the dominant phenotype.
