ORA finally debuted a project that they’ve been working on for a year (well, actually a decade if you count the total time they’ve pursued this clownfish variety). We finally have commercially available captive-bred F1Amphiprion leucokranos, the White Bonnet Clownfish, and from reading the info it would seem that these are purely Solomon Islands provenance fish as well. ORA initially suggested that these fish would be released in early winter 2014, but as ORA now states, this is one of the slowest growing clownfish they’ve produced (so much for hybrid vigor?). You may have seenthese fish teased at MACNA 2014, and now they’re finally available for purchase through ORA retailers.
One of the most interesting findings is that the Leucokranos, while showing considerable variation in the offspring patterns, do not show “throwbacks” to either of the suspected parental species,A. chrysopterus或者A. sandaracinos. I know this is surprising some; people seem to have the notion that hybrid offspring should range between the parental forms on a continuum between the parental species, particularly in a 2nd generation mating. That said, the reality is that in the first generation of a hybrid, only 50% of the genes are contributed by each parent, which means the resultant hybrid offspring in such a primary hybrid are relatively uniform (this is why, for example, MOCHA Clownfish are consistent in their appearance in my opinion).
同样，如果您将任何两个后代并将它们交配在一起，则它们是父母物种的50/50混合物，但仅贡献了其遗传物质的50％。从理论上讲，尽管假设两种鱼都可以随机贡献仅从一个父母物种继承的所有基因，因此也许导致一条类似于倒退的鱼，但实际的结果是，F2代是另一回合遗传硬币抛弃和改组。因此，您似乎获得了更多的相同，而不是某些人期望的“连续性”。简而言之，我认为的几率在天文学上很小，这意味着虽然化妆可能会漂移到45％的物种，而在某些后代中，另一个物种占55％，但或多或少地将50/50的分裂在随后的一代中保留下来除非采用选择性压力或直接的背部交叉，否则将施加到父母物种上。
ORA also instituted一个非常新颖的分级概念with the introduction of their White Bonnets. This move garnered a little bit of negative sentiment in online circles, which I might sum up best as “really, we need to have premium and ultra vs. standard White Bonnets”? I understand the sentiments, but in a “species” with such variation in the offspring, the fact is that people will have preferences for one form vs. another. ORA certainly believes that a headstripe which connects to the back-stripe is the most idealized form, so that is the grade at the “top” of the spectrum.
Me? I like the ones with a cap and a cheek mark, separated. And that’s really the point – the grading system isn’t about marketing HYPE, it’s about marketing and managing the expectations of ORA’s customers. ORA’s approach is very objective vs. subjective…no hype involved (in my opinion) and it’s really no different than sorting out the “misbarred” Ocellaris and selling them separately from the ones with “good” bars.
