Lessons
14Mendel's Laws of Inheritance
Mendel's pea plant experiments, the Law of Dominance and the Law of Segregation, and solving monohybrid crosses with Punnett squares.
Genetics: Inheritance and Terminology
The language of genetics: hereditary traits, genes, alleles, homozygous and heterozygous, phenotype and genotype, and how alleles are passed from parents to offspring.
Genetics: Law of Dominance
Mendel’s law of dominance, complete dominance crosses, Punnett squares and test crosses, and the phenotype and genotype ratios of the P1, F1 and F2 generations.
Genetics: Incomplete Dominance and Co-dominance
Incomplete dominance and co-dominance compared with complete dominance, including genetic crosses and phenotype and genotype ratios.
Genetics: Pedigree Charts
Solving genetics problems with pedigree charts, including the genotype and phenotype ratios of the generations in the chart.
Genetic Engineering: Stem Cells
Genetic engineering, the use of stem cells in medicine, and the ethical concerns around cloning and genetic modification.
Genetics: Sex-linked Diseases – Haemophilia
Haemophilia as a sex-linked disorder, genetic crosses involving haemophilia, and the inheritance of sex-linked alleles.
Genetics: Mutation – Sickle-cell Anaemia
Sickle-cell anaemia as a gene mutation, its inheritance pattern, and solving genetic crosses involving the sickle-cell allele.
Genetics: Blood Groups
Multiple alleles and co-dominance in human blood groups, solving blood-group crosses, and blood-group inheritance.
Genetic Counselling
The role of the genetic counsellor, how family history and genetic testing inform reproductive decisions, and pedigree analysis.
Cloning
The definition, process, types, advantages and disadvantages of cloning.
Recombinant DNA Technology
RDT definition, the steps of insulin production, and products made using RDT.
Genetically Modified Foods
Genetic engineering in agriculture, GM crop examples, plus pros and cons of GM foods.
Genetics: Sex-linked Alleles — Albinism
Definition, symptoms and treatment of albinism, carriers vs albinos, and common myths.
