From genes to phenotype

A gene is a length of DNA that codes for a polypeptide or functional RNA, and an allele is a version of a gene. Your genotype is the set of alleles you have, while your phenotype is the set of characteristics you can observe.

Step-by-step lessons covering Edexcel A A Level Biology Epigenetics, phenotype and continuous variation for A Level Biology. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
