In this video, I explain ALL of the content required for the "Inheritance" section for AQA A Level Biology. This includes: genotype + phenotype, concept of heterozygotes/homozygotes, multiple alleles, monohybrid crosses, test crosses, dihybrid crosses, codominance autosomal linkage, sex linkage, epistasis and the chisquared test. Time stamps are in the comments.
I also go through a few exam questions and explain their mark schemes.

All the content in this video crosses over with other exam boards.

Please leave a comment if you have any questions, I'll be more happy to answer them!!! :)
