Document Summary
Herbert spencer coined this phrase in 1864 after reading darwin"s on the origin of. Used it to compare his economic theories to darwin"s biological ones. Phrase does not accurately portray the mechanism of natural selection: not just survival! Most also reproduce leading to higher fitness. Rephrase as survival and reproduction of the fittest = the one that is most likely to survive and reproduce . : the individuals that are most suited for an particular environment (most adaptive traits) have the greatest probability of surviving, reproducing, and having their offspring reproduce (highest fitness) Hardy-weinberg equilibrium: p^2 + 2pq+ q^2 = 1 p^2= dominant q^2= recessive. 36% a1a1 48% a1a2 16% a2a2 p= p^2 + pq =0. 36 + (o. 50)*(0. 48) = 0. 60 (1-p)=q q= q^2 + pq= 0. 16 =(o. 5)*(0. 48) = 0. 40. We know p^2 so just square root it and get p (only if you know it is in equilibrium)
