Question

what races of humans have the most and least genetic diversity and why?

Answer 1

Ostensibly, Sub-Saharan Africa has the most human genetic diversity and the same has been shown to hold true for phenotypic diversity

Answer 2

why ?

Answer 3

Africa contains the most human genetic diversity anywhere on Earth, and the genetic structure of Africans traces to 14 ancestral population clusters that correlate with ethnicity and culture or language.

Answer 4

here's what the academics have to say:
According to a 2000 study of Y-chromosome sequence variation,[10] human Y-chromosomes trace ancestry to Africa, and the descendants of the derived lineage left Africa and eventually were replaced by archaic human Y-chromosomes in Eurasia. The study also shows that a minority of contemporary East Africans and Khoisan are the descendants of the most ancestral patrilineages of anatomically modern humans that left Africa 35,000 to 89,000 years ago.[10] Other evidence supporting the theory is that variations in skull measurements decrease with distance from Africa at the same rate as the decrease in genetic diversity. Human genetic diversity decreases in native populations with migratory distance from Africa, and this is thought to be due to bottlenecks during human migration, which are events that temporarily reduce population size.[30][31]

Answer 5

which is just a bunch of info

Answer 6

Will u please make it easier to understand ?
Avoid just copy paste !

Answer 7

the fact remains that "in Africa there exists a great deal more diversity than elsewhere" a diversity that apparently decreases the further from Africa a population is sampled.Again evidence shows that African populations contain about 100% of human genetic diversity, whereas in populations outside of Africa diversity is much more reduced. pro exemplar the population from New Guinea only about 70% of human variation is captured.

Answer 8

hahaah @Abhisar i'm surprised anything i say is difficult for you to understand man, youre like Einstein: omniscient

Answer 9

Genetic diversity in africa is greatest because humans were originated there. Human community there is oldest. Older the population, greater will be the mutation in gene pool. Hence more will be the genetic variations

Answer 10

are u getting my points @brparadox ?

Answer 11

lol

Answer 12

so in that case the further away from africa (or people with the least african heritage) are likely to retain the least genetic diversity according to Abhisar

Answer 13

that should help answer your question of least and most

Answer 14

as for the why, I'll leave that up to Abhisar and read his response later because that guy knows his business and you'd be a fool not to listen to him

Answer 15

@PRAETORIAN.10 \(Do~You~know, To~Respect~people~?\) \( Some~eyes~Always~watch~you~as~we~have~a~sack~of~complains~!\) \(Be~nice~!\)

Answer 16

??? I just said he was smart...I didn't know saying someone is smart is insulting???

Answer 17

are you telling me that saying Einstein was smart is insulting?

Answer 18

because i will honestly tell anyone that they're a fool if they dont listen to Einstein

Answer 19

and there is nothing disrespectful or abusive about the truth

Answer 20

and by the way @koikkara that sounds like a threat so despite your 84 hit point intelligence score or medal score or whatever it is, i must ask you not to threaten me without reason. i said he was smart end of story. if HE finds it offensive he can tell me.

Answer 21

@PRAETORIAN.10 Sorry dude, we call it as Friendly Warning, as it does not have nothing to do with threat, an act of coercion wherein an act is proposed to elicit a negative response...Hope u can understand those... Or just go to Google and search what it means...lol

Have A Nice Day !!

Answer 22

Also, its just a place to answer the asker's doubts not a place to mention personal opinions.
