Let's think about the possibility that SL-Edged and Cinnamon were different alleles of the same locus. I am absolutelly sure that this possibility has already pup up in somebody's mind
. I propose you all to list the reasons for and against this hypothesis.The first and more important reason against this idea comes from the inheritance pattern: SL Edged is dominant, and when years ago it was described, people thougth that it was an autosomal mutation. It was only recently that it was described as a dominant SL mutation.
In our usual way of thinking every mutated allele behaves always the same way respective to the wild allele. Ex: SL-Ino and Pallid are both recessive respectiv to the wild allele. So in our minds we do not automatically accept the possibility that a dominant mutation and a recessive mutation could be different alleles of the same gene (locus). But this is not true and I will try to prove it:
Let's imagine 3 different alleles of the same locus showing the following order of dominance: A > B > C. Now let's imagine their behaviour depending which one becomes the most prevalent in different environements:
1. A is the most prevalent ... it means that A is the wild gene. The behaviour of B and C respective to A would be recessive.
2. B is the most prevalent ... it means that B is the wild gene, and , thus, A will behave as dominant and C will behave as recessive.
3. C is the most prevalent ... it means that C is the wild gene, and both A and B will behave as dominant.
In the present situation, the second possibility would explain that SL-Edged (A) behaves as dominant respective to the wild gene (B), and that Cinnamon (C) behaves as recessive respective to the wild gene (B).
As Deon likes to say: Comments, please.
Recio
) and when Cinnamon is added we can not see any difference. The edged pattern could be a "side effect". It would be similar to adding SL-Ino and NSL-Ino (the "side effect" here being at the eyes level).
