Answer from: dina18

Pp and pp

the genotypic ratio is 2Pp: 2 pp

Explanation:

When doing the cross you can consider the possibility of the outcome through a punnet square or probability.

A punnet square is the best option to do so, however.

Make a grade with four boxes and place one allele of one genotype over each box like this

P p

Add the letters of the other genotype next to the boxes.

P p

Now put one allele in the box, like you are multiplying the letters

P p

p Pp pp

Now you have done a punnet square

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.
