The correct answer is D) 0,81
When there is Hardy-Weinberg equilibrium like in  this  case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. And we have:
p²+2*p*q+q²= 1       <em>p+q= 1     p=1-q</em>
q= 0.1     p= 1-0.1= 0.9
p²=0.9²= 0.81
 
        
             
        
        
        
The stronger survived and the weaker passed on... Those with a weaker immune system had trouble with sickness and usually ended up passing on but those with strong immune systems were stronger and healthier and lived.
