In a population of tree frogs, the allele that causes yellow eyes (y) is dominant over the allele that causes orange eyes (y). if 85% of the frogs have yellow eyes, what is the frequency of the dominant allele?

Allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y)

Y = 85% = 0.85 and

y = 100% - 85% = 15% = 0.15

f(y) = square root of y = √y = √0.15 = 0.387

frequency of the allele that causes orange eyes = 0.387

Once we know the value of y, Y + y = 1

Putting the value of y, we get

Y = 1 – 0.387

Frequency of the dominant allele that causes yellow eyes = 0.61

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

i think that you are smart and you should fit for it out
