A population of frogs consists of 81 percent with speckles (recessive) and 19 % without speckles (dominant). What are the frequencies of p and q alleles if this population is in Hardy-Weinberg equilibrium? Show work.

The correct answer would be the frequency of the recessive allele in a population  

The Hardy-Weinberg equations are  

p + q = 1

p² + q² + 2pq = 1

p stands for the frequency of a dominant allele in a population.

q stands for the frequency of a recessive allele in a population.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
