All organisms reproduce, or make more organisms that are similar to themselves. ______________________ also involves the passing of traits from one parent to offspring. The passing of traits from parents to offspring is called _____________________________. A _____________ is a set of instructions for an inherited trait. For example, a gene may contain the instructions that determine the color of a person’s eyes. The genes are located on structures inside a cell called _____________________________. After scientists recognized that chromosomes store the genetic information, they began an intensive search to learn more about the structure and chemical composition of chromosomes.. By: Keith King.
