Punnett Squares are really cool once you know how to do them! You can work out the inheritance of offspring using the parent alleles. Visit www.emmatheteachie.co.uk for my Inheritance workbook. • INHERITANCE WORKBOOK: https://emmatheteachie.co.uk/product/... • INHERITANCE MINDMAPS: https://emmatheteachie.co.uk/product/... • Make sure you’ve watched the “INHERITANCE - KEYWORDS” video first, as we’ll be jumping right in with these! • We’ll go through an example of a blue-eye mother and brown-eye father having a child. I’ll show you how to draw a Punnett Square and then work out the probabilities of the genotypes and phenotypes the offspring can inherit. • Foundation Tier: you’ll be given the Punnett Square / more structured questions. • Higher Tier: you need to be able to work out all of the steps yourself. • And finally, you’ll learn the male and female sex chromosomes and my tip on how I remember them. • COMMENT BELOW: Do you love or hate Punnett Squares?! • Please SUBSCRIBE here for more GCSE Biology revision: • / @emmatheteachie • And if you’d like to support me in making these videos, you can gift me a “virtual coffee” on ko-fi - here is the link for you to take a look at! • https://ko-fi.com/emmatheteachie • Thanks for watching, • Emma
