Gene
Gene explained in an easy to understand way:
Imagine trying to find a specific recipe in a huge cookbook to bake your favorite cake. Just like that recipe contains all the instructions needed to create that specific cake, a gene contains the DNA instructions needed for a specific trait. In this analogy, the cookbook is like the chromosome, the recipe is the gene, and the cake is the trait; just as the recipe guides you to make the cake, the gene instructs the development of a particular trait.
Practice Version
