"Not by cross-pollination, no." He smiled. "Next class will be focusing on grafting. I can think of a hybrid studies class for next term, however. Anyway..."

He tapped the board. "In truth, there are two genes which determine eye color as far as muggle scientists know. And as I said, genes are really like an on-off switch that works in pairs. One gene is for brown eyes, the other is for green. Only here is dominance ever an issue... because unlike blue eyes and brown eyes, which are actually part of the same gene, brown eyes and green eyes are entirely separate genes."

He erased the Bl from the board and replaced it with Gr. "But, you'll also notice that a person's eyes can range from green to brown, but rarely, if ever, blue to green. This is because while brown is dominant over green, it will also cause a blending of color." He wrote Bl below both Br and Gr on the board, then doubled them. In the middle of each Br/Bl or Gr/Bl pairing, he drew a light switch. Under that, he drew an eye, which currently looked blank.

Code:

Br  Br  Gr  Gr
 ^   ^   ^   ^
 |   |   |   |


Bl  Bl  Bl  Bl

"For instance..." he tapped the eye, which turned light brown, "if we were to turn off one brown switch..." He tapped a switch and it moved to the 'off' position. The eye turned a dark green, though still rather brown-ish. "There, you see? To get blue, we just turn them all off." He turned off the other brown switch and the eyes were a slightly lighter green. A green switch turned off and the eye was a rather light green, though still not pale. Turning off the last switch, the eye was blue at last.

"That turned out looking better than I thought... I'd just come up with it now." Shaking his head to keep from getting further distracted, he looked back to the class. "Of course, the Amore Fraterno has a wide range of colors, as well as two special types I mentioned before. Who remembers what those were?"
