"Genetically they're twins" confuses me, because it implies identical twins, but Eva and Lilly don't look the same. If you meant them to be fraternal twins I would word that differently.

That wasn't the point of the comment. They meant that they were twins but nothing alike. Clearly they aren't identical twins as they aren't identical. I believe the comment was more like "they may have the same Gene's but they couldn't be more different". Also, if you're gonna post every single grammatical error, maybe you should just send a message to the creator listing them instead of filling up the entire page with individual mistakes.
I meant similar Genes, like siblings would have. However, it is possible that they are monozygotic twins because the only thing I noticed really different was the hair color, could just be dyed (which usually happens with identical twins as they want to differentiate themselves). Either way, my point was I got the point of the statement which was to say the two sisters were polar opposites.
