Hey Yall!!!
I have witnessed the beauty in the teachings of inheritance patterns and wanted to know how I and up with hazel eyes from a brown eyed dominant mother and a green eyed recessive father ( my dads dad had green eyes but his other siblings did not).

I'm not too familiar with the HSC Course, but I'm pretty sure that -- like the VCE course -- it is simplified. We use eye colour in high school because it's an easy concept to think about. In reality, eye colour is controlled by more than a few alleles (if a trait is controlled by more than one gene it is called polygenic). It goes beyond the HSC course

However, I asked my teacher this exact question years ago, and she sent me this :) luckily I was able to find it again haha. Again, though, this isn't relevant to the course, it's just purely for your own sake
