D. Learned behaviors do not directly affect natural selection because they are not inherited.
This is true because learned behaviors can be taught to the offspring but do not come within them the way instincts do.

Answer:
The correct answer is 160. 
Explanation:
Based on the given question, the total number of fruit flies is 1000, of which red eye flies are 640. Thus, the number of sepia eye flies will be 1000-640 = 360.  
On the basis of the Hardy-Weinberg equation, p+q = 1, in which p is the rate of recurrence of one allele, that is, dominant and q is the rate of recurrence of the other allele, that is, recessive.  
q^2 for the population is 360/1000 = 0.36, q = 0.6.  
Therefore, p = 1-q = 1-0.6 = 0.4.  
The frequency of homozygous dominant allele is denoted by p^2 = 0.16.  
Hence, the number of homozygous dominant for red eye color would be 16% of 1000 which will be equal to 160.
