pH Biology · Genetics & Inheritance Mastery Workbook

Genetics rewards students who can lay out a Punnett square cleanly — and lose marks for those who can't. This 23-page Mastery Workbook builds from DNA and chromosomes through to autosomal and sex-linked inheritance, then on to mutations, natural selection and the evidence for evolution.

What's inside

·       65 exam-style questions on DNA, alleles, Punnett squares, sex linkage, variation and evolution.

·       Step-by-step Punnett squares worked through, including carrier and X-linked crosses.

·       Sex-linked inheritance (colour-blindness, haemophilia) carefully explained.

·       Worked solutions for every question, with “common slip” notes.

·       Topic overview plus 10 mixed exam-style questions to finish.

Who it's for

Year 10 and 11 students sitting GCSE Higher Tier Biology — particularly those aiming for the top grades, where the harder Punnett square and probability questions live.
