I just wanted to thank you so much for all your exam revision videos. You made it so easy to understand, and your methods were so engaging…. I owe a lot of my A* Biology IGCSE grade to you, and I just wanted to thank you :) You’ve also helped to inspire a love of biology in me that will continue even though I’ve taken a different study path. Thank you!!!

[@adeolaoni7672]

quick question, you keep saying gene is passed on and then change to say gametes are passed on which is correct or are they the same thing?

[@salmaan4521]

gametes have the genes so it is the same thing

[@ahamedakmal7104]
