I got a question that comes from the 1990 released test #61 that I'm completley lost on

61. In a population that is in Hardy-Weinberg equilibrium, the frequency of a recessive allele for a certain hereditary trait is 0.20. What percentage of the individuals in the next generation would be expected to show the dominant trait?
a. 8%
b. 16%
c. 32%
d. 64%
e. 96%

The key says E is the answer but I don't see why or how can you please exlain how this is so... I believe that the reason why I can't get this answer is becasue it's asking of the individuals of the next generation in which case I don't seem to know what to do.... thanks!!!
