How genetic information is copied, recombined and expressed, and how reproduction strategies shape the variation a population carries.
These are the statements the Biology syllabus makes about Module 5: Heredity. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Asexual reproduction copies a genome cheaply and quickly; sexual reproduction pays a cost to shuffle it. Which strategy a species uses is a trade-off between speed and variation, not a measure of advancement.
Mitosis produces identical cells for growth and repair; meiosis halves the chromosome number and recombines genes. Knowing which produces variation, and at which stage, is what these questions test.
Transcription copies a gene into mRNA; translation reads it into a chain of amino acids. The sequence-to-structure-to-function chain is the whole idea, and it is where most marks are won or lost.
Independent assortment, crossing over and random fertilisation produce combinations no parent had. Quantifying the possible combinations is a routine calculation.
Techniques that read or manipulate DNA: sequencing, PCR, gel electrophoresis and cloning. Each answers a different question, and choosing the right one is the skill.
Monohybrid and dihybrid crosses, dominance, codominance, sex linkage and pedigree analysis. A pedigree is evidence to be read, not a diagram to be described.
Modelling inheritance with a test cross or simulation, then judging whether the observed ratios are consistent with the predicted ones given sample size.
Extracting DNA and evaluating why each reagent is used, and what its presence or absence would change in the outcome.
HSC Biology - Trial Paper Shape is 100 marks in 180 minutes. Questions on Module 5: Heredity are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Biology uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Module 5: Heredity opens the Biology course. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Biology dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
