TRIANGLE BLUE GRASS a jewel in the Guppyzucht* * This Information Credit and Thanks for http://www.dampopo.com * *The Guppy trunk with the trivial name "Blue Grass" exists in Japan already since approx.. 1985 and began
to become more well-known only 10 years later also in Europe. Since now already some breeders possess
this trunk in Germany, it will throw time a somewhat more exact view of the history and genetics of this trunk,
which lead back far into the 70's.
If we are occupied with the Blue Grass, we do not come around around the r - factor.
The "normal" (grey) Guppy possesses the characteristics RR. The reason why the R twice occurs is, which
it gets one of the father and which others of the nut/mother.
The initials R red stands and comes from the English term talks for the color.
While the capital letter R stands for Dominant, the small letter marks the Rezessive. The r - Factor with
the Guppy does not stand thus for the function of " development of red". What means that?
Now, in the case that carries our Guppy RR in itself, he will show the most beautiful colors and naturally
also the color red to train will be able. Both Wildguppys and most Hochzuchten which we meet, are in the
majority RR animals.And which passes if parents the r - factor in the play brings? How then does this Rr
lookanimals?
In this case the red is suppressed and the blue color shows up.
And if now an animal of both parents the r - factor gets (thus an rr-animal develops)?
Then we have to do it with an animal of the basic colour blue. These animals only few colors to train can,
are well-known.
How did the Blue Grass come to its r-factor?
In the 80's the r-factor was introduced by one halfblack/blue Guppy (called in Japan neon Tuxedo)
made of Singapore. The Japanese crossed these animals with its females some fine "Glass sample"
showed. These animals with the nearly transparent schwanzflosse (therefore glass) had their origin
likewise in Singapore (in the 70's).
By the crossing neon Tuxedo with the glass bulls one received a fish to that the today's Blue Grass
saw already quite similar.
The Blue Grass became further sophisticated, and/or those examination and the blue colouring were
intensified.
We assume thus that you acquired a couple Blue Grass. How will the descendants of this pair probably look?
The Blue Grass male is an in any case Rr-animal. With the female one cannot be safe. It could be a RR or a Rr.
And exactly this is also the reason why with their crossings only 50 % of a throw Blue Grass - animals are.
Look at yourselves the following crossing patterns. They do not come over 50 % Blue Grass in a throw.
"to be reached, one can probably hardly speak if not at least 80 % of Reinerbigkeit", says there most breeders.
Thus functions however now times with the r-factor. The r-factor lies not on the Geschlechtschromosomen, but on
the Autosomen. Therefore RR, Rr is bound and rr not to a sex.
If you liked to thus reach 100 % Blue Grass, this is also possible. By it a red male (and/or talk Grass) with basic
colours blue females pairs of (see pattern).
Now will understandably why it talk Grass and the females of the basic colour blue to need, if you liked to
come to better results. The looking so inconspicuous blue females are thus nevertheless completely useful.
Cross calmly once also different males (e.g. Snakeskin, Moscow Snakeskin/filigran, red/Mosaic, etc..) with the
blue females. The results are quite substantial!
With the successful breed of Blue Grass one may never forget thus the genetic background. Normally the
Blue Grass of animals (Rr) without problems grows up, like its red brothers and sisters (RR). If an illness in the
basin should arise however nevertheless, the Blue Grass is possibly susceptible and endangered rather
(does not apply however to all Blue Grass of trunks).
How can I receive now my Blue Grass trunk in the long term?
I personally think that it is meaningful the RR males to remove rr-males and rr-females from the basin
(despite the results of table 3).
What would pass if I RR couples and Rr-couples in same number, in the same basin would hold would like?
Purely statistically seen the 1 following result isto be expected in the F:
RR: Rr: rr = 9: 6: 1
The number of the red animals increases thus.
And if we now in each case RR -, Rr and rr-couples in the same number, in the same basin would hold?
The following suggests the F 1:
RR: Rr: rr = 9: 18: 9
(or also 1: 2: 1).
Half of the animals are thus Blue Grass.
"that is marvelously", you will possibly say. But as previously mentioned the Vitalitaet of the RR is quite
different -, Rr and rr-animals. The experience shows that the red RR animals increase in number.
The selection (and/or the removal of the unwanted animals) must be thus constantly accomplished
(you to be able also one talk Grass - trunk parallel develop).
Respect with the choice of the Blue Grass - males on a fine dotting. This should be recognizable also
in the dorsal fin.
Males with a metallic gloss (nearly silver) are the better.
The females should show much blue in the moving and schwanzflosse. Fehlfarben (usually yellow)
in the tail fin beginning, must be selected. Try with the time to differentiate also the RR females from
the Rr-females to. That is not simple, but with a sharp eye and little experience might succeed to you that.
Address also the breeders, who already accomplished some crossings with Blue Grass. Also
Blue Grass - trunks can from breeder to breeder vary because a crossings with other color impacts
were already accomplished.
The END...
