Genetics question

i usually use the branching system in my mind, when figuring out questions that arise on my forum.

For pewter to lesser pastel, i go like:

ok, so, disregarding the other genes and focusing on pastel its 25% normal, 50% pastel, 25% super pastel. Then i split it and put in cinnamon. 12,5% normals 12,5% cinnamons 25% pastel 25% pewter 12,5% super pastel 12,5% super pastel cinnamon (sterling).

That is about as far as i can go using my mind alone, by just thinking hard, and it came about through practise. Thats what i pull out of my nose on short notice, so to say. I dont need pen and paper so far, i think hard and spit out the answer.

one gene missing, lesser. i take the string, which is: "12,5% normals 12,5% cinnamons 25% pastel 25% pewter 12,5% super pastel 12,5% super pastel cinnamon (sterling)" and manipulate it further, do one more split.

and i go from that to 6,25% normals 6,25% lessers 6,25% cinnamon 6,25% cinnamon lesser, 12,5% pastel, 12,5% lesser pastel, 12,5% pewter, 12,5% lesser pewter, 6,25% lesser super pastel, 6,25% super pastel, 6,25% super pastel cinnamon (sterling), 6,25% lesser super pastel cinnamon (lesser sterling).


no matter which method you use, the results are the same! This is quite important. You can use whatever method you like, if it works, it will give the same results other methods give. If you calculate one way and your results fail to match the results derived by any other method, your calculation is wrong.

Also note that in my method, and also the "Branching system" method, it does not matter with which gene you start, if you do it all correctly the result will be the same. In between it may look much different depending on how you arrange it and with which gene you start first, but the end result is the same in any case, and is similar to the end result of the punnett square.
