Key language for monohybrid inheritance

Humans are diploid, so most body cells contain two homologous chromosomes and therefore two alleles of each gene. A gene is a length of DNA at a fixed locus, and different versions of that gene are called alleles.

Step-by-step lessons covering Edexcel A A Level Biology Monohybrid inheritance and genetic screening 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.
