Evidence: loss of genetic diversity necessary to getting pure breeds.
In your opinion. {citation required for the loss being necessary; that's what you are trying to prove.}
Evidence: loss of genetic diversity result of population splits in the wild.
In your opinion. {citation required; let's see the data.}
Evidence: You can't get new phenotypes unless you get rid of alleles for other phenotypes
In your opinion. {citation required}
Evidence: Cheetah, unique cat with fixed loci, which is the end result of loss of genetic diversity in the formation of new species. It could be created by one drastic bottleneck or it could be created by a series of population splits occurring from each former daughter population.
In your opinion. {citation or data or explanation required for "could be created"}
Evidence: Pod Mrcaru lizards whose large heads and new digestive system formed within thirty years of reproductive isolation on an island where they had been released. Evidence of what happens by reproductive isolation alone over a short period of time. We can assume drastically reduced genetic diversity from the simple fact that only five pairs of lizards were the founding population.
In your opinion. {citation required}
Evidence: Jutland cattle evolved four different races or species by reproductive isolation alone over a very short period of time. Evolution works fast. It creates new subspecies by eliminating the alleles for other phenotypes. The four different subspecies of cattle in this case may still possess sufficient genetic diversity for further evolution. or they may not.
In your opinion. {citation required}
SO far it's just unsupported claims. Of course you cannot produce anything more than that.
