A long long time ago when I was in school. Yes I did go to school, I think that I did anyway. When I was in Agriculture class I was taught that if you crossed two purebred hogs that the off spring would out produce the purebreds by ten percent???????????????????????????????
Is this same thing happening in society today?

You get purebreds by breeding out all undesired traits. This is a loss of information. Unfortunately, with all the inbreeding necessary, you also get some undesireable traits. By mixing breeds, you are adding back dominant genes that cover the undesireable traits, thereby producing offspring that are stronger than their parents. So it is quite possible that this "hybrid vigor" also results in more offspring.
As for people--I don't know if the "races" (I believe there is only one race--the human race) are concentrated (genetically) enough to have many "purebred" problems (there are a few--spherocytosis among Europeans, Tay Sachs among Jews, hemophilia among European royalty, etc.), so the vigor gained by intrracial marriages probably would not be noticed. And too many people use birth control for any difference in fertility to be noticed.

Yes, of course, no race can escape Darwin!
Your question about hogs relates to mixing of diverse genotypes which results in a larger gene pool and a better chance for adaptation. This difference would not be significant for several generation even with monitored breeding.

This topic is purely based on traits that define race today. We may all breed and intermix but there will always be a big margin in how people compare to one another. To say that we will all be one similiar skin color and body type is probably never going to happen. There is too much diversity in life.

mix race marriage will involve two different races of individual. for example, an American marries an Asian. The physical appearance of their offspring will depend on the genetic recombination or the genes of the two parents when expressed in the child. thus, the child, can be more like an american or an asian depending on the dominant or more expressed genes.
about the hogs, that is what you call hybrid vigor. hybrid meaning the cross between different species or variety, or in human, race. vigor means the overall health or vitality of the offspring.
in rice, hybrid vigor is used to produce hybrid rice, that is, it produces yield greater than the yield produce by its two parents separately.

yes, it is destroying us. Our country is getting dumber and dumber each year.
If you look back at Egypt back in the BC era, It was a thriving country but racial integration and interracial marriages destroyed it.
Before the racial integration, they had electricity and flying machines.
But due to the integration over the years, everything was lost.
The only thing remaining was a mixed up species with no clue to how anything was built, made, etc...
They had very little history and they couldn't write. All they could do was draw pictures.
If it wasn't for the Nordic People along with the Japanese, We wouldn't have anything that we have today.
If everything keeps going like it is with the interracial breeding, we are going to be breed back into the stone ages again.
So I think the interracial breeding along with interracial relationships should be stopped as soon as possible before everything is lost again.
If everything is lost, then there will be no return this time.
We will be nothing but a bunch of bushmen with wooden spears as weapons.

depend how do you applly to your life cause both need to take and give, of course little bit will be a changing on your life. cause culture was different basicly, but when u get married with someone with different race then what ever your pathner is that means you ready to accept what ever the person is without effected to your physically and mentally.

It's not going to be long and we'll all be mixed race. Whites are already a minority in Nebraska. I don't feel any dumber yet.

yes, pretty soon everyone will be of the mixed race, my 3 kids are and there the cutest kids there is nothing wrong with it be with who ever makes you happy

I think you should do more research before drawing such conclusions. We are talking about humans not pigs.
