Consider a population of frogs. allele b1 codes for spotted frogs; allele b2 codes for non-spotted frogs. b1 is dominant to b2 .

the allele frequencies on the mainland are b1 = 0.75 and b2 = 0.25.

the allele frequencies on the island are b1 = 0.55 and b2 = 0.45. there are 170 frogs on the island.

during a storm, 30 non-spotted frogs come to the island by floating on debris. what are the new frequencies of b1 and b2 on the island?

enter your answer as two numbers (each to two decimal places), separated by a comma. (example: 0.56, 0.44)
