... These characteristics are called traits. Traits depend on the types of proteins that the 4 bases (A,C,G,T) make up. Parents pass on copies of their DNA to their offspring. The DNA from each parent combines to form the DNA of the offspring. How the offspring develops depends on the instructions ...
