Genetics is the highest-scoring unit in Class 12 biology and the one students find hardest to picture. This course builds it up from Mendel's pea plants to the structure and copying of DNA, then ends with the evidence for evolution.
- Worked crosses with ratios you can check
- Comparison tables for quick revision
- Practice questions in the NEET format
