An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. during the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. a biology student tabulates the following information. genotype plumage color % of population allele controlled phenotype ff or ff dark green 84% f (dominant) dark green plumage ff white 16% f (recessive) white plumage using this information, the student plans to use the hardy-weinberg equation to predict the allele frequencies in future peacock generations. why would her research advisor have a problem with this?

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.

a. to encourage apoptosis

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
