Biology Glossary

allele

In Genetic inheritance, allele means the specific Unit 4.6 idea used to answer this objective: students must explain the terms allele, dominant and recessive. Keep the term curriculum-specific by applying this boundary: DNA is the molecule; a gene is a functional section of that molecule. Do not use allele as a vague inheritance word; link it to Reproduction and explain the exact role it plays in AQA GCSE Biology.
