It can only be 50 % as the female has was homozygous

It was 50% however it was the woman who water heterozygous. The man had the condition hence he was homozygous recessive. The woman was heterozygous therefore she was a carrier.

Actually love that exam. Cardiac cycle woopwooop. Didn't specifcally like the differences between replication + transcription and the 3 mark on the positioning of 35 and 52 for lysozymes.

I described and explained what happened at each stage, which valves were open/closed and why, and where the highest pressure was, relating to points on the graph.
