Each visit shows a fresh randomly-picked question from the live AQA GCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for AQA Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

In Andalusian chickens, black feather (C^B) and white feather (C^W) alleles are codominant. What is the phenotype of a C^B C^W chicken?

Accepted Answer

Blue (grey) feathers — Because the two alleles are codominant and both expressed simultaneously, the C^B C^W chicken produces an intermediate-looking blue or grey plumage, often called 'blue Andalusian'. This is a classic example of codominance at the level of pigmentation blending in feathers.
