Genetics is one of the most reliably tested chapters in NEET Biology. Mendel's laws (segregation, independent assortment), test crosses, dihybrid ratios, sex-linked inheritance, blood group genetics, and pedigree analysis appear every year. Evolution is mostly factual recall (Darwin, Lamarck, Hardy-Weinberg) but sometimes asks calculation questions on allele frequencies.
