Somewhat Rare Rescue

[ammerman19]

I don't think they are so much culled by the parents but thought it was do to natural selection and them standing out. on a rocky bottom a yellow/white fish is going to be much easier prey to spot vs. a dark colored fish with a broken pattern that will blend in more. My .02 cents. And good post Modest,

I'm sorry I thought "recessive" meant less than normal? I will study more before I enter topics I need some fine tuning on...

Homozygous dominant, heterozygous, and homozgyous recessive all have two alleles (one from each parent). So there's no "less", just different alleles.

There are some rare circumstances where an organism can actually end up with only one allele, but it doesn't pertain to this discussion.

There are two color morphs, EBJD and the pink, also called gold. The normal coloration technically isn't a color morph, as it's the WT (Wild Type) color. I haven't seen an albino JD, but that would be a third, and different, morph from the pink/gold.

It's late and I just got off work, but genetically speaking animals don't lack or have an extra "color" gene, they have a mutation in their genetic sequence that turns off or on color production through several different pathways.



You're kind of close but not really at all. How about not posting unless you know your facts? Bad information is worse than no information.

Here's a quote, as I'm not a pro at albinism





Correct for leucism, not xanthism. Gold JD's = leucistic. It should read something like





Xanthism is different than albinism and leucism, which is where you have an excess of yellow pigmentation. Similar with the EBJD (excess of pigment, not a lack).

So, to conclude, the gold/pink JD is a form of leucism, not albinism or xanthism.

The common pink cons are leucistic. The jag formerly owned by bolty is xanthic (see the difference? Pale (lacking all color) vs. yellow (lacking all but yellow))

This is probably too much information for most, but if you actually read it all and have any questions, feel free to ask. I love genetics.

heres an idea how about you bite me i was just trying to help. how about a round of applause for being ignorant!

In the wild most albino or "off" color morphs, especially when they grow slow like ebjd's, are indeed culled, preyed upon what have you. In the home aquarium, they are often times culled due to being runts because they grow slower than normal jd's.

I don't think they are so much culled by the parents but thought it was do to natural selection and them standing out. on a rocky bottom a yellow/white fish is going to be much easier prey to spot vs. a dark colored fish with a broken pattern that will blend in more.

Sounded better the second time?

 

[ammerman19]

yes I think so

Very nice pick up! I can't wait to see him all healed up!

I was wrong like I said. I have never studied genetics, or wikipedia'd it. My comment was a representation of my misinterpretation of what I thought I have been reading...lol I am seeing the light now though and I "get it". It does not bother me to be wrong. This thread is now PACKED with something we all should know thanks to you.

Unless I am missing something, that seemed a bit uncalled for.

maybe stated a little bluntly but altogether it is true. Bad info is worse than no info
