What has breeding dogs in the same family got to do with breeding in the same race?

Narrows the gene pool.


http://en.wikipedia.org/wiki/Genetic_diversity

Genetic diversity plays a very important role in survival and adaptability of a species because when a species's environment changes[/b], slight gene variations are necessary to produce changes in the organisms' anatomy that enables it to adapt and survive. A species that has a large degree of genetic diversity among its population will have more variations from which to choose the most fit alleles. Increase in genetic diversity is also essential for an organism to evolve. Species that have very little genetic variation are at a great risk. With very little gene variation within the species, healthy reproduction becomes increasingly difficult, and offspring often deal with similar problems to those of inbreeding. The vulnerability of a population to certain types of diseases can also increase with reduction in genetic diversity.

Listen my friend, they did a series of tests on willing irish folks to test their dna as a matter of identifying how far back they could trace these peoples roots. Their roots have remained in Ireland for thousands of years. In fact the university for DNA in Dublin said the typical irish person's DNA has not really altered much at all. These are strong, dynamic, resolte, strong, passionate people, being white and irish hasn't harmed these people  ;D

The Overfiend:
Genetic principles apply to all species, not just humans.

'Race' dosn't really matter. Well, I mean it does and it dosn't. The real issue is genetic diversity, not 'race' itself, but they are both related but not to the extent we tend to think. The discovery that only 8% genetic difference separates the major races has led some scientists to proclaim that race is biologically meaningless. Skin, hair and eye color are non-concordant in that they are not necessarily expressed together. For example skin color and hair texture vary independently and lighter hair colors are associated with Europeans, especially Northern Europeans, but blond hair is found amongst a limited, small number of the black populations of the south pacific, particularly the Solomon Islands and Vanuatu.

The Irish folks probably have a diverse and large genetic pool to begin with already or they branched out and spread around the world before any inbreeding began to occur  (although how do you account for the Leprechauns?  :D)

With any people that remains an isolated island for long enough, eventually common characteristics emerge and a distinctive 'race' is born. This is what geneticists call the 'Founder Effect' (see http://en.wikipedia.org/wiki/Founder_effect)

In extreme cases, the founder effect is thought to lead to evolution of an entirely new species. Now if Ireland remained an isolated island from the rest of the world, chances are in another few thousand years they would begin to distinctively resemble an entirely different race. But with peoples that remain isolated, the tendency is for the gene pool to shrink (like the Amish in the US, who tend to let few newcomers into their community and marry within their community, their community has higher rates of deformities like multiple fingers and shit)

However globalization tends to counteract this tendency by exposing isolated ethnic groups to a wider variety of people and cultures.
