This long sequence serves two functions. First, part of it specifies, like a code, exactly what the constitution of the protein molecules of our body will be. These proteins comprise the structural elements of which our bodies are made, the materials of our cells and tissues, and also the enzymes and hormones that make our metabolism possible. Corresponding to a particular sequence of A's, T's, C's, and G's, there will be produced by the machinery of the body a long molecule; a protein made up of simple elements, the amino acids.

Q. of the adopting parents, who always do much better on I. Q. tests than the biological parents. What is at stake here is the difference between correlation and identity. Two variables are positively correlated if higher values of one are matched with higher values of the other. The ordered set of numbers 100, 101, 102, and 103 is perfectly correlated with the set of 120, 121, 122, and 123 because each increase in one set is perfectly matched by an increase in the other. Yet the two sets of numbers are clearly not identical, differing as they do by 20 units on the average.

The answer to that question depends on some issues in basic genetics that were undecided in the early history of hybrid com, and until 30 years ago, one might have argued that the basic biology of corn production is such that only hybrids would provide the added yield. However, we have known the truth of the matter for the last 30 years. The fundamental experiments have been done and no plant breeder disagrees with them. The nature of the genes responsible for influencing corn yield is such that the alternative method of simple direct selection of high-yielding plants in each generation and the propagation of seed from those selected plants would work.
