A paleontologist is trying to determine the ages of several fossils using different methods. When using carbon dating, the main problem is:
A. It can only be used at night
B. It can't determine the age of really old fossils
C. It works on living organisms only
D. It can only be used to date animal fossils

The diagram shows the results when two parents are crossed. the letters represent alleles for a trait that is controlled by three different genes. which best describes this inheritance pattern? multiple allele because a trait is controlled by three different genes polygenic because the offspring have alleles from both parents multiple allele because the offspring have alleles from both parents polygenic because a trait is controlled by three different genes
