Now, it turns out that normal wings that we're going to designate with blue uppercase V is dominant over the recessive vestigial wing, which we're going to designate with purple lowercase V. And by the same token, the color gray is dominant over the color black. So the color gray, we're going to designate with red uppercase B. And the color black, we're going to designate with orange lowercase B. Now, the normal wings and our color, the wing gene and the color gene are linked to one another. And what that basically means is they are found on the same exact chromosome. So to see what we mean by that, let's take a look at the following diagram.
