<span>Fruit flies and pea plants may seem boring and simple, but the basic principles of genetics were worked out using those organisms. Humans follow the same patterns of heredity.

Second, human heredity involves the same relationships between alleles—dominant and recessive interactions, polygenic traits, and sex-linked genes, among others.</span>
The nitrogenous bases (guanine,cytosine,thymine,adenine) code for our traits.
