After four generations, the following results were obtained. Higher Education professionals play a key role developing AP courses and exams, setting credit and placement policies, and scoring student work. This chart shows recommended scores for granting credit, and how much credit should be awarded, for each AP course. For example, if a question asks you to describe mutualism, the grader is going to look for a definition of mutualism to award a point, and then an elaboration of mutualism, like an example, to give an additional point.

Experiments by the following scientists provided critical information concerning DNA. Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene. Explain how the events of meiosis I account for the observations that led Mendel to formulate these laws.

An organism is heterozygous at two genetic loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. Explain how these alleles are distributed by the process of meiosis to gametes.
