Along the chromosome, we can have thousands of different types of genes. And in this particular diagram, we have only six genes. So we have a red gene, we have a green gene, we have our blue gene, the light green gene, the dark purple and the light purple gene. And each one of these genes basically codes for its own protein that is used to express some type of trait. So, for example, this gene can code for a tall plant. And so this is the hygiene.
