Feedback and what you get

Questions are marked automatically as pupils answer: a sound and a character reaction show straight away whether they are right, and correct answers earn points, with a results screen at the end. Sentence-writing tasks are for pupils' own answers and are not marked automatically.

AA, AS or SS? Teach pupils to predict what children can inherit — and why genotype testing matters. This 22-slide interactive lesson on genetic crosses takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Genetic Crosses and Sickle Cell Genotypes in GCSE Biology

Pupils recap alleles, genotype, phenotype, homozygous and heterozygous, then apply them to the sickle cell genotypes AA, AS and SS. They draw Punnett squares for carrier crosses such as AS × AS, express outcomes as probabilities, percentages and ratios, and compare sickle cell with cystic fibrosis. The lesson finishes with sex determination using X and Y chromosomes and a reveal on why the AS genotype is common where malaria is widespread.
