Chromosomes: the basis of heredity: WAEC Biology Past Questions and Answers
What the WAEC syllabus covers in Chromosomes: the basis of heredity
Our summary: Chromosome and DNA structure, and how genes separate and recombine between generations.
- Structure (Candidates should observe chromosomes in permanently prepared slides of cells and root tips of onion or lily. Candidates should study the structure of DNA and gene replication using models and charts.)
- Process of transmission of hereditary characters from parents to offspring (Segregation of genes at meiosis and recombination at fertilization should be used to explain the process of transmission of hereditary characters from parents to offspring.)
