AQA A level Biology help, please!

11

Hi, I need some help with this question from 2017 paper 2.
It's question 10, there's a passage relating to Alzheimer's disease.
I didn't understand question 10.3 and 10.6, why couldn't it be the founder effect? Could it be a genetic bottleneck or would they mark against it?
And why is it two dominant alleles?

Sorry I couldn't attach the actual question.

Thank you for any help!
