Hi

I got a family pedigree diagram question in a January 2019 Human Biology practice paper I took, this was the question:

This is how I gave my answer in the practice exam:

This is what the question's answer looks like in the mark scheme:

In the textbook for IGCSE Human Biology and Biology, we're taught to use squares for males, circles for females, shaded icons for those affected by a trait, and unshaded icons for those not affected. The marking scheme doesn't show this.

Would I lose marks for drawing the diagram like the textbook (with a key) or am I good to go?
Did I get anything else wrong in the formatting of the diagram?

Thanks for the help.

I think you should be fine, especially because you used a key. In IGCSE exams I did (with pearson), they used the squares and circles.
If you are really worried, mention it to your teacher because the syllabus could have changed or something.

Haha, this is reassuring. Thank you. (I'd ask a teacher but I'm studying this as an external candidate lol)
