RE: OT - White Cloud Genetics
There are a lot of simple recessives that are extremely rare in nature
because they are deleterious to survival. A great example is albinos
(amelanistic), which do occur, but generally don't survive as well, except
in our tanks, where some folks will select and protect the mutation. I
think that is the case in White Clouds as well, long fins wouldn't seem
like much of an advantage when fleeing bigger fish !
Some long fin traits are not simple recessives, but partial dominants,
veiltail angelfish for example. With angels, you can tell precisely what
the genotype is, the so-called "super veils" are homozygous (and double
ugly, IMO), while the heterzygotes are normal veils (and look OK if well
maintained). Any angel with no trace of a veil tail is sure to be
homozygous for non-veil.
Long fin White Clouds have been around for a long time. I remember an
article in TFH when they were the "small" format (70's I think) and were
called Meteor Minnows. I recall desiring them greatly, but they were
completely unavailable. Now I have some, and they actually spawned! It's
kind of like fulfilling a childhood dream. If I figure out the genetics,
maybe I'll write an article for TFH about my experiences.
Please excuse the exuberance. I'll think I'll go give them some more live
food, they deserve a treat.
