Serial dilution / dilution series calculation worksheet for A-level Biology.
Part of a growing bundle of worksheets aimed at improving maths skill confidence for A-level Biologists.
21 marks of AS/A2 exam style serial dilution / dilution series questions.
Full mark scheme and serial dilution explanation/method with worked example included.
Of particular relevance to AQA required practicals 3 and 6. However, the questions are not exam board specific and would be useful to any practical involving serial dilutions.
Percentage change and Hardy-Weinberg calculation worksheets also available.
Detailed worksheet covering (virtually all) possible autosomal linkage exam questions. Could be used as homework or as an assessment (due to the low number of past exam questions on this particular topic).
Includes a chi-squared question and links to/revision of meiosis
Made with AQA in mind, but the specifications for OCR and Edexcel are pretty similar for this topic, so would be beneficial to those specifications as well.
Mark scheme included.

There is some ambiguity when it comes to mark schemes on questions such as accuracy/precision - with different exam boards sometimes having slightly different answers. I have tried to include the most appropriate answer on the flashcards, but if anyone disagrees with any of the answers - please do send me an email at the address below and I will alter the answers accordingly!
Please note that I can accept no responsibility for your final exam grade should you choose to use these revision resources. These resources are intended to help students actively revise, but students should be aware that a high proportion of the marks in your exams are AO2 and AO3 marks and students should therefore use a variety of resources and techniques in preparation for all of the question styles that will be encountered in the exam. Whilst these resources have been written with past mark schemes in mind, there is no guarantee that future mark schemes will be the same.

Meiosis summary worksheets for AS / A-level Biology (process has been simplified to include only two pairs of homologous chromosomes):
Students can cut out each worksheet around the dotted edge and glue/tape the sheets together to produce a large summary sheet covering the entire process of meiosis.
PDF includes two versions:
3 page version which includes details on individual stages of Meiosis I and II.
2 page version (more suitable for AQA) that provides an overview of Meiosis I and II and does not go into details regarding the individual stages.
I have included diagrams representing the chromosomal content of cells during interphase (both prior to, and after DNA replication). I have drawn the chromosomes in interphase in the same way as the chromosomes during the meiosis (even though in interphase, the chromosomes have not yet condensed), this is just so students can clearly see what is happening to the number of chromosome.
Both versions are designed for students to colour the chromosomes to represent maternal and paternal chromosomes (and also the results of crossing-over).
Versions with completed text are included, if you are short of time and would like to provide the sheets as handouts instead. However, please note, students would still need to colour the chromosomes to represent the maternal/paternal chromosomes and the outcome of crossing-over.
An example of completed colouring is included on the last page of the PDF.
Exam style question worksheet:
36 marks of exam-style questions covering the A-level Biology topic of meiosis.
Written for the AQA specification, but the majority of the questions are relevant to all exam boards. Non-disjunction has intentionally been set as the last question, allowing it to be easily removed for those exam boards which don’t include this sub-topic.
Questions have been designed with the intention of covering as many permutations as possible with regards to meiosis exam questions, but without repetition.
Useful as a homework / self-assessment / revision task before an end-of-topic test.
Includes full mark scheme.
Suitable for Triple or Combined Science & suitable for all exam boards.
