Which is not a condition for Hardy–Weinberg equilibrium? Answer-
-Absence of gene flow
-Absence of differential survival among genotypes
-Random mating of individuals with respect to genotype
-Absence of genetic drift that would cause chance fluctuations of allele frequencies
-Small population size

Hardy-Weinberg equilibrium requires no immigration or emigration, a large population, random mating, and no spontaneous mutations (all of which are virtually unavoidable in nature). Natural selection would violate these conditions.

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times
