Your plurals would be grammatically correct, but there is nothing wrong with the sentence as such. As FumbleFingers mentioned, its just style!
1No. Grammmatically you could make a case for (optionally) using plurals there, but stylistically I'd say singular is better. I might put the indefinite article before "harmful effects" rather than "genetic", but it's all just stylistic choices. – FumbleFingers Reinstate Monica – 2014-08-23T17:09:14.290
Compare *Claims about the harmful effects of cellphone radiation are more speculation than documented fact.* You wouldn't move the article there. – FumbleFingers Reinstate Monica – 2014-08-23T17:14:08.550
