Please show some effort in solving your questions on your own before you ask us for help. We're volunteers, we are not supposed to do your entire work. Also, if your question fits in one sentence you probably didn't explain it enough.

• Percentage across your cohort? In public databases?
• What's a SNP type?
• Which plot do you have in mind?

We can't guess these things, so you'll have to explain what you want, what you tried and what exactly didn't work.
