This assignment and unit are overall awarded a distinction. This is Assignment C of Unit 11 and will talk about human inheritance and predicting genetic traits. In this assignment I have given examples of Mendles pea plants, explained F1 and F2 generation, and carried out and investigate Dihybrid and monohybrid inheritance in mazes have concluded my findings using chi-squared and conclusions. I have used drosophila flies, cystic fibrosis, hemophilia, blood group in this assignment as examples.
