A flower farmer purchased one million dollars worth of seeds from Class E Seed Company and was told these seeds (F2 generation) would produce perfectly pure
purple plumes of plump plum flowers because the plants that produced the seeds
(F1 generation) were themselves purple and from a large 100% genetically uniform
generation. After planting the seeds, the farmer found twenty five percent of the
flowers were white, not purple. How can this be? The farmer thinks the grandparent
flower plants (P generation) are to blame. Do they have a case to settle with Class E
Seed Company? See if you can figure out the genotypes of the grandparent plants to
complete your analysis. Assume purple flower color is dominant, white flower color is
recessive, and that the current generation of flowers is the

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

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
