The different varities of humankind that are classified as a 'race' were genetic adaptations to environmental factors that provided a genetic advantage over others that did not exhibit the adaptation. Just as 'races' are somewhat different from each other in appearance, there are other genetic traits and dispositions to certain diseases or resistance to certain diseases that are reflected statistically. These would also be due to genetics.
From a Biblical perspective, there are not different races of humans on Earth. There is only one race. The Bible says in Acts 17:23 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; So you can see it is clear God made us one race, and that was from Adam, the first man.
There are not different human races, there is only one. There are different ethnic backgrounds.
They have different allele frequencies.
yes, DNA was mapped from a multitude of humans, different races, twins, and even people with genetic abdnormalities were collected.
the genetic coding of humans is different. thats why chimpanzee is different from humans. as simple as that.
It is a catergory of mechanisms that prevent two or more populations from exchanging genes. The Mule and the Hinny are two examples. --Better answer! it's when a type of species is separated for too long so they can no longer reproduce with each other because each of them have adapted and changed depending on their environment. humans almost went through reproductive isolation, but we were not isolated long enough, which is why we have different races and different types of races can still mate with each other. hope i helped(; It decreases allele frequency.

it is like different races of humans have different languages. only they can understand each other. but if we really tried i bet we could translate it.
The DNA of all humans is essentially identical and allows breeding, despite a difference in the continental origin of the parents.

Yes, different races can MARRY.
There are not different human races, there is only one.

There are many different races that are held besides foot races. These races include bike races, swimming races, and competence races.
venezuela is a melting pot with many different races.
People of different races make babies together and that baby will have mixed races.
There are over 10,000 trillion alien races/civilizations (with 100,000+ per galaxy; excluding humans) in the Animorphs universe.
