Old Biology Homework

I was looking through some stuff when I found some old homework sheet that was about corn snakes (I think I was sick when I got this paper as it was not completed).

The teacher that assigned that homework would probably have a cow if they saw just how far cornsnake genetics have come since then! "Bonus points - Determine the potential phenotypes if you bred a diffuse hypolavender motley het opal with an amber stripe het butter bloodred. Include percentages."
 
It's like some strange sort of foreshadowing...little did you know that, back then, you'd one day be so involved with corn snakes! :laugh:

I wish I'd had an assignment like that back in my biology classes...we only got to do the fruit fly punette square thing. :/
 
Assignments like that lead to corn snake addictions - they recommend researching corn snake genetics on the web and that will only lead young impressionable minds to forums like this where they will find themselves wanting one of every color... lol

A single dominant gene that makes normal melanin pigment! The biochemists and geneticists showed that idea was wrong decades ago. :(

What the author should have said was that it takes a whole gang of genes working together to make normal melanin pigment and a single recessive mutant to stop the whole process. Just like a breakdown in one machine in an assembly line stops the whole thing.

When we teach genetics to beginning students, we always oversimplify things... it's just the best way to learn the "basics." Afterwards, advanced students who pursue further courses will learn all the details.

I always teach students single locus, single trait at first... even though such situations are rare. If we were to jump right in to teaching them the reality of genetics, few would understand.

I have no problem with simplifying a concept if is done right.

It's been a few years, but as best I can remember, by the third grade I understood the concept of teamwork. And in this day of organized Little League baseball, football, and soccer teams, the idea of genetics as a team effort involving many genes shouldn't be difficult to put across. A mutant gene is simply the team screwup.
