Question

All of the following statements support the hypothesis that humans cannot be classified into biological races except:
a. There is more genetic diversity within a racial group than average differences between racial groups;
b. Alleles that are common in one population in a racial group may be uncommon in other populations of the same race;
c. Geneticists can use particular SNP alleles to identify the ancestral group(s) of any individual human;
d. There are no alleles found in all members of a given racial group;
e. There is genetic evidence of mixing among human populations occurring thousands of years ago until the present.

Accepted Answer

Hello everyone. And in today's video we have the following problem which one of the following statement is in favor of the hypothesis that humans cannot be classified into biological races. Remember these races are used biological subdivisions within a species. Now, in order for these subdivisions to take place, these races or these groups of people must be very different to each other. And so how will they become different within a species? And that's by having unique alleles or just different alleles. Now, if this is true then answer choice A a little is unique to a particular race is going to be true and it's not going to be they cannot. X statement is going to be a correct hypothesis. However, if we have that these certain races have unique close to each other and we have for example, answer choice C there is evidence of continuous population admixture. So there is this just mixture between different populations or groups of people over periods of time. If this population admixture takes place, then races of humans will not be able to have unique alleles and races will not be able to form just because this population and mixture is going to mix the alleles between different populations, preventing them from having unique alleles. So because of this, this is actually true statements, humans are a species that has been able to just mix in terms of its population over periods of time. And so we're going to highlight this because because of this, this is the reason why we do not have any biological races in terms of human, because we cannot find a leo's that are unique to each race. Due to this, make sure that has taken place over periods of time. So this is going to be the end of the video, and I really hope this video helped you.
