Master Genetics and Meiosis for Grade 12 CAPS or NSC — Paper 2. Clear notes, worked crosses, crisp meiosis diagrams, plus exam-style data questions and memo keywords 🧬🧪📈 ▶️ Grade 12 Life Sciences Playlist:    • Matric Life Science - Exam Revision (Grade...   What you will learn ✂️ Meiosis: purpose, phases Meiosis I and II, synapsis, bivalents, crossing over, chiasmata, independent assortment, non-disjunction; where it occurs and why it increases variation 🧮 Genetics basics: gene, allele, genotype, phenotype, homozygous vs heterozygous, dominant vs recessive, codominance, incomplete dominance 🌱 Monohybrid and dihybrid crosses: parental genotypes, gametes, Punnett squares, F1 ratios, test cross, probability tips ♀️♂️ Sex linkage and pedigrees: X-linked patterns, carriers, affected males, reading family trees ⚠️ Errors and mutations: non-disjunction Down syndrome, gene mutations point and frameshift, effects on proteins 📝 Memo keywords: crossing over, independent assortment, gametes, genotype, phenotype, probability, test cross, sex-linked, pedigree, non-disjunction Exam technique — Paper 2 Crosses: always show phenotype → genotype → gametes → cross → F1 ratio Ratios and probability: simplify neatly, use fractions or decimals where asked Meiosis drawings: label phase, homologous chromosomes vs chromatids, show crossing over clearly Pedigrees: state pattern, justify with two clues carriers, affected males, skipping generations Data questions: quote numbers and units, then conclude with a statement that links back to the hypothesis How to use this video Watch the lesson ▶️, pause at each question ⏸️, answer first ✍️, then mark with our checklist ✅ to maximise your score.
