Question

Help with grammar, punctuation and spelling errors:
I think there is a possible association between the hair color brown hair and brown eyes. The total number of people with brown eyes in the chart is 20 while 11 of those, might I add more than half, have brown hair as well. The reason there is an association between dark hair and dark eyes is because the genes for both hair and eyes are extremely close together on the same chromosomes making it very rare for just one, to switch.

Answer 1

"hair color brown hair" You say hair twice, you might want to revise that.
"might I add more than half" You should probably take out 'might I add' and just say "more than half".
You also want to delete the comma after 'just one' at the end of the paragraph.

Answer 2

Is this better? "I think there is a possible association between the brown hair and brown eyes. The total number of people with brown eyes in the chart is 20 while 11 of those, more than half, have brown hair as well. The reason there is an association between dark hair and dark eyes is because the genes for both hair and eyes are extremely close together on the same chromosomes making it very rare for just one to switch." @naxve

between brown hair and brown eyes*

Answer 4

I would add a comma after chromosomes, but everything else looks good. :)
