Which of the following is least likely to produce genetic variation in the offspring of an individual?(1 point) a cross over event during meiosis that creates a new combination of alleles in the gametes

independent assortment of chromosomes during meiosis that creates a new combination of alleles in the gametes

a DNA replication error caused by DNA polymerase in a body cell of the individual

the random fertilization of an egg cell by a sperm cell during sexual reproduction

The correct answer is c

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.

The answer is !

Yes yes yes yes very good
