NEW AQA GCSE Trilogy (2016) Biology - Inherited disorders & genetic screening
This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the 'Inheritance, variation and evolution ' SoW.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop:

This lesson begins with an introduction to inherited disorders, particularly the two examples students will need to learn about - polydactyly and cystic fibrosis.

Pupils will then be given information on either of these two disorders and will be asked to complete a fact file on the one they have been given using a set of criteria provided. Once they have completed one of the fact files they will need to pair up with someone who did the other fact file to share information.

Pupils will then be given further information about the inheritance of these disorders and whether it is controlled by a dominant or recessive allele. Pupils will need to draw genetic diagrams for each of the disorders given a set of example parent genotypes, and work out the probability of the offspring inheriting the condition.

The next part of the lesson focuses on embryo screening, firstly pupils are introduced to the two ways in which embryos can be screened for genetic conditions - amniocentesis & chorionic villus sampling. The next task pupils will need to think > pair > share ways in which these two methods which be controversial, identifying the positive and negative effects on the baby and family. For the final activity pupils will be given a set of opinion cards in groups, they will need to read the viewpoints, discuss as a group and write a short summary paragraph on their opinion of genetic screening in embryos.

The plenary task is for pupils to write three summary sentences of what they have learnt this lesson using as many key words from the list provided.
