Please round your answer correctly to 4 decimal digits.

c. You are studying skin color in a population of frogs at Lake Johnson. Your original population of 350 frogs had a green allele frequency of 0.4 and a brown allele frequency of 0.6. An animal rights student group "rescued" 50 lab frog that had a green allele frequency of 0.7 and released them into Lake Johnson where they mixed with your population. The frequency of the green skin allele in the population after migration is.
