Bn genetics aren't really well understood at this time. Wed like to think it as simple as Darwinian genetics and in some instances it is by in others it seems more complicated.
There could be different color modifiers carried on different genes. This is best exhibited in angelfish who's genetics are abut better known. FOr instance, and I'm not saying it's right as I can't remember exactly but, the gene for ghost us carried on a different gene then the gene for blushing thus when you combine angelfish thy carry ghost genes with those that carry blushing you get blushing ghost angelfish as some fry. Again this isn't exactly right as I can't remember what combinations yield what results on angelfish but it's an example where you can get intermediates.
L144 is a leucistic form of a particular ancistrus species. The "L144" we currently see is a leucistic form of ancistrus cf cirrhosis. Same color form, different species.
Long fins could exist in nature but as it may hinder swimming ability it may nit be in nature long.
Bristlenose is another name for bushynose.
ok so what you are saying is that is it as confusing to you as a lot of others and you need to find out more and fish genetics are not straight forward.
The angel fish thing is what made me think if fish genetics were the same as human genetics. Also what makes one gene stronger than another so one shows and another doesn't?
Do you mean same species , different colour form? Is the "fake/so called" L144 ancistrus cf cirrhosis? To be that breed does it have to have spots and be brown since the albino bristlenose is ancistrus cf cirrhosis.
So L144 is a hybrid? OR a new species altogether? OR ancistrus cf cirrhosis with no spots and black eyes but yellow?
So this L144 , where did it come from? I am not winding people up just trying to get what exactly this plec is and where it originally came from.
Are you sure the L144 is not just a **** up and then someone managed to sell it on as a L144 then people believed it and then this **** up became accepted as a breed of plec.
