So I don’t have a copy of Campbell’s underhand, but a quick google search for its table of contents brought up the ToC for 7e.
Chapter 9, pg 161 covers epigenetics, p 162 gene linkages, Ch11 covers gene methylation.
I’d find additional specific examples, but that’s all that’s laid out explicitly in the table of contents.
- mehrdadn 7y agoConfused, are we looking at the same edition? I don't see an explicit mention in the ToC [1], and Chapter 9 is "Cellular Respiration: Harvesting Chemical Energy"... are you saying that's where they mention epigenetics?

- arkades 7y agoThis is the ToC I found: https://www.pearsonhighered.com/assets/preface/0/1/3/4/0134812948.pdf https://www.pearsonhighered.com/assets/preface/0/1/3/4/01348...
- mehrdadn 7y agoYeah you're looking at the wrong book. That's copyrighted 2019, not 2004. And not sure what "7e" means (doesn't seem to be the same as "7th edition") but it's Campbell Essential Biology, not Campbell Biology.
- arkades 7y agoSo, the edition you’re linking, you’ll likely find epigenetics in ch21, genetic basis of development. That’s usually where the older books discussed methylation and acetylation.
- mehrdadn 7y agoYeah, I've been trying to dig something up. Here's all there is in the 8th edition -- like just 3 sentences: https://books.google.com/books?id=5nZlDwAAQBAJ&pg=PA358&lpg=PA358&dq=%22Researchers+are+amassing+more+and+more+evidence+for%22&source=bl&ots=FuKIc5MWzD&sig=ACfU3U2CvIjI8P0jpSwwczGilyXIKFRBzg&hl=en&sa=X&ved=2ahUKEwjezbWNle_iAhVidt8KHZEIAlcQ6AEwAnoECAkQAQ#v=onepage&q=epigenetics&f=false https://books.google.com/books?id=5nZlDwAAQBAJ&pg=PA358&lpg=...
- arkades 7y agoThey didn’t generally refer to it explicitly as epigenetics - they tended to cover the exact mechanisms. Check out pg 358’s dedicated subsection to methylation, for example. The word epigenetics won’t be mentioned, but it’s one of the classic epigenetic mechanisms.
- mehrdadn 7y agoI'm not sure if I understand that section correctly, but it sounds like it's talking not about inheritance across organisms, but about replication within an organism?
- arkades 7y agoMethylation and acetylation of sex chromosomes is inherited. In somatic tissues it affects downstream development; in gonads, it becomes a heritable trait.
