Document Summary

In a hypothetical population of 1000 frogs there exists a gene with two alleles. 280 of the frogs are homozygous dominant (dd), and 220 are homozygous recessive (dd). what is the frequency of the d allele in the population: 0. 47, 0. 50, 0. 53 (correct, the answer cannot be determined from the data provided. Scientific theory is different from our everyday use. Theory is not a guess or a hunch. No hierarchy, but if there was then theory > law. This is a description, it does not say why. Gravity is real, it is true, it can be observed, it can be testedas is the case with. If life originated on earth in the distant past and then evolved, we should see evidence in. If creatures share a common ancestry, then we should see transitional forms. We should see evidence of retrodictions and vestigial characters. We should be able to see evidence of natural selection.
