|
|
Term
| Hardy-Weinberg Law (and examples) |
|
Definition
p = f(A) and q = f(a)
p+q = 1
(p+q)2 = p2+2pq+q2

|
Definition
Ethnic Groups -
People that share common:
Customs.
Cultural characteristics.
Language
--------------
Racial Groups -
Used to describe the geographical distribution of human populations.
Historically based on “biological” differences between groups of humans.
The popular definition of “race” has no meaning in biology.
The term “race” has to often been used to imply “differential worth.” |
