Answer:
BBBB = 0.64
BBBG = 0.20
BGBG = 0.16
Explanation:
Genotype frequency = individuals of that particular genotype / total number of individuals
Genotype frequency of blue geckos (BBBB) = 160 / ( 160 + 50 + 40 ) = 160/250 = 0.64
Genotype frequency of turquoise geckos (BBBG) = 50/250 = 0.20
Genotype frequency of green geckos (BGBG) = 40/250 = 0.16
