There is another trick to another breeder in generating local yorkshire walnut. Different from the previous tricks, they are no longer married yorkshire males and females the original import, or even crossed the yorkshire local walnuts with males females. Step that is used is to produce saplings of intersecting the first filial or commonly called Walnut indukan F1.Genetically, F1 will have a 100% yorkshire Blood imports, so the local yorkshire puppies who later produced also remains 100% yorkshire blood. In addition, sensitivity to the environment will be much better than his parents.

The breeders also does not stop the experiment at any time. They try to combine or cross indukan Walnut walnut with F1. The results obtained with similar crosses Walnut yorkshire import local walnuts with males females. Yep, the local yorkshire puppies are much better against new environment adaptation rather than previous methods.



Conclusions from the above explanation is a process crosses Walnut yorkshire can be done by several methods including:

1. indukan males and females Copulate of type import yorkshire Walnut

2. indukan Splice males of species with indukan import yorkshie females from the local walnuts

3. indukan Splice F1 yorkshire Walnut indukan walnut with F1 male yorkshire females

4. and last, copulate Walnut indukan F1 yorkshire males with female local Walnut indukan

A little tip for bird chirping PAL at home who want to try printing a local yorkshire Canary himself, if you want to marry a pure yorkshire, indukan kind of import, F1, F2 or whatever it was then all the resulting saplings will have traits of yorkshire. But if you want to cross with the local walnuts females then any child is going to inherit traits that brought his mother.
