A summary / notes suitable for revision of the Genetics unit (covered in DP1, HL Biology with core elements that are covered in SL Biology too). The document was made with help of in-class notes, various websites and presentations from Bioknowledgy, but all information should have been rephrased at least slightly. The entire part of the syllabus (for the Exams in May 2017) that was covered in this unit is discussed; all statements have been explained, skills and applications are not mentioned however.
Detailed notes for the subtopic 'Neurons and synapses' including action potential steps and transmission of nerve impulse at a synapse. Referenced from Pearson, Oxford course companion and other IB recommended textbooks.
