Question about Pleco genetics. Long finned vs Short finned

Hey everyone, so as many of you know I'm really into Plecos and currently have two varieties: L144 Blue Eyed Yellow and a male Albino Long Finned. I would like to get L144 Blue Eyed Yellow Long Finned as an end result. I know albinism is a recessive gene and both parents have to have the gene in order to have albino fry. The myth goes that L144 aren't pure to begin with since the first male was bred to another bristle nose variety or something like that lol. Now I'm curious, is the long finned gene recessive as well and do both parents have to have the gene in order for the fry to have long fins? If I bred a short finned L144 Yellow Blue Eyed Pleco to a Male Albino Long Finned what would the fry outcomes be? I know they wouldn't be albino since the female does not posses the gene (I got the original L144 from a reputable breeder and have bred my 6 new breeding colony from them). Just curious if anyone could provide some insight on this. Thank you!

 

Long fin is a dominant gene in every species that I am aware of. Homozygous for long fin will produce extra long fins in most species, as well.(e.g., Super Veil Angels)

 

That's something I'd assume to be recessive. I feel like in the wild a long finned individual wouldn't survive as long since he wouldn't be able to hide or move as well as the short finned friend

 

I bred a male short finned yellow blue eyed pleco with a female long finned brown pleco. She has a recessive albino gene because when she had babies with my albino male, half of her babies were albino.

When she had babies with the yellow blue eyed male NONE of her babies were albino. So the yellow blue eyed pleco clearly has no albino gene. There is a mixture of short and long finned babies though. One regular finned parent and one long finned parent. The other batch of babies was also a mix of long and short finned babies. And in that case both parents had long fins....

That's my experience.

 

When u bred the blue eyed yellow male to the regular female did you get yellow blue eyed fry as well?

Unfortunately not! I was hoping so.

My plan now, considering all his babies have the yellow blue eyed GENE, is to breed one of his long finned daughters back to him in hopes of getting the same result as you...a long finned yellow blue eyed pleco!

I might have to go that route also but growing them out to breeding age takes for ever lol

Long fins are not a mutation that shows up in the wild. For some reason it does occur in aquarium specimens on occasion. I know for certain that long fins are a dominant trait in Livebearers, Angelfish, Rams, and some species of Corydoras. If two longfins have shortfinned young, then it has to be a dominant, otherwise they couldn't be carrying a hidden gene for normal fins.

That's very interesting. I'm always amazed by genetics and thanks for the clarification!

I Hear you!! That is exactly how I feel right now! I am so anxious to make this happen. We will have to stay in touch and keep each other updated on our "projects"
