What do your text materials say?
Since this is not my area of expertise, I searched Google under the key words "'metabolic block' 'phenotypic effects'" to get these possible sources:

http://www3.interscience.wiley.com/cgi-bin/summary/117869530/SUMMARY?CRETRY=1&SRETRY=0
http://www.stantonbury.org.uk/Students/Science/Cooksey/Mod2.pdf
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
