Lepiej nie bo pozycjonowanie strony wyżej chyba nie może pójść :p ,natomiast przeciążenia serwera przy burzliwej dyskusji doprowadzi do awarii :D
Z mojej strony jestem ciekawa bo to co ja mam w akwarium to są starej daty crystale ,nie mieszane. Nie mam PRL tych "magicznych" .Moje zawsze mnożyły się w kotniku ,z tego słynę hehe,więc z praktyki trudno mi uwierzyć w pewne rzeczy.
Tu chyba na mkbreed próbowali odpowiedzieć na to pytanie:

F1 F2 F3 F4 ……?
F1, F2, F3, F4, is a name we give to the offspring of shrimp that are born from parents of different blood lines. For example, the offspring from A and B will be called F1 ( unstable gene ). The offspring of F1 male mixed with A or B female is called F2 ( slightly stable gene ) F2 male mixed with F1 female or F2 female will be called F3 ( more stable gene ). F3 male mixed with F2 or F3 female will be called F4 ( stable gene ).
Why is F4 the most stable?
The basic of genetic algorithms was first proposed by Professor Holland of the Michigan University in 1975, It is based on the principle of natural selection and the survival of the fittest. So if genetic traits carried are what you desire, the characteristics shown on the organism is also optimal.
Using the genetic algorithm for selective breeding:
1: Keeping the most desirable traits from the parents and passing it onto the offspring, not losing the traits in the offspring.
2. Mating: All genes are randomly selected between two of the most elite male and female generations and part of the genetic info is exchanged. With the accumulation of the desired genetic information, we hope to achieve superior offspring.
3. Mutation: All genes randomly selected from one elite female generation, randomly selected point mutation, by changing the value of this elite female generation mutation point, we look forward to a better mutation of a new offspring .
Upon completion of the above three methods, the desirable genes retained participate evolution produce new offspring of the next batch, and the remaining poor genes were eliminated, this method is called "Eugenics Strategy", which can guarantee the offspring will be better than the previous generation.
Using this method, MK-BREED was able to pass on 57% of the most desirable shell pattern traits in the F4 generation.
What are PRL, PBL?
PRL : Pure red lineage
PBL : Pure black lineage
There’s 2 types of "Pure Line Shrimp". 1st type is shrimp that are not mixed with any different types, does not produce any golden bee or colors that are different than the parents. 2nd type is shrimp that are not mixed with any different types, offspring produced are exactly the same as parents. However, after many years of breeding and discussion, it is concluded among all the breeders around the world that type 2 is difficult to verify and therefore is not a true pure line.
