Genetic algorithm initial popuplation

I use GA to minimize an objective function with 20 variables. I noticed that ga always produces initial population with small distance between individuals, usually at [0,1] while lower bound is 0 and upper bound is 90. I would like ga to produce the initial population more uniformly. Is this possible? My code:
n=20;
A=zeros(n,n); %linear constraint x1<=x2<=x3<=x4<=...<=x20
b=zeros(n,1);
for i = 1:n
for j = 1:n
if(i+j==n+1)
A(i,j)=-1;
end
if(i+j==n)
A(i,j)=1;
end
end
end
b(n)=90;
LB=zeros(n,1);
UB=90*ones(n,1);
options=gaoptimset('creationfcn',@gacreationuniform,'PlotFcns',{@gaplotbestf,@gaplotscores,@gaplotbestindiv,@gaplotdistance},'Display','iter');
[x,fval,exitflag,output,final_pop]=ga(@(x) obj(x),n,A,b,[],[],LB,UB,[],options)
