In the last section we learned about breeding Dominant gene animals to codominant gene animals. As we've already learned, the only difference between Dominant and Co-dominant genes is that Co-dominant genes are able to produce Super forms and dominant genes are not. So, in this next example we are going to breed a Pastel Ball Python to a Pastel Ball Python, which are both Co-dominant gene animals. We will code each of them with the letters "NP".
This calculation shows us that 25% of these offspring will be normal Ball Pythons, 50% of the offspring will be Pastel Ball Pythons and 25% will be Super Pastel Ball Pythons. Super Pastels would obviously be the most desirable offspring we could hope for in this clutch.
So, what is so great about Super Co-dominant gene animals? Let's find out. This time we will breed our Super Pastel Ball Python to a normal Ball Python. As always, we will code our normal with the letters "NN" and we will code our Super Pastel with the letters "PP".
As we can see, from simply breeding a Super Pastel Ball Python to a mere normal Ball Python without any special genes, we were able to produce a clutch with 100% Pastels. So, we've now learned that breeding any Super Co-dominant gene animal to a normal guarantees us that 100% of the offspring will be the Co-dominant gene, which the Super Co-dominant parent derived from and there will not be any normals.
To conclude this section, we will breed our Super Pastel Ball Python to a regular Pastel Ball Python. We will code our Super Pastel with the letters "PP" and our regular Pastel with the letters "NP".
This time, 50% of the offspring will be will be regular Pastel Ball Pythons and 50% of the offspring will be Super Pastel Ball Pythons. Thus, once again we have produced a whole clutch of more desirable offspring without any normals.
