should be red, vermillion and cinnabar. because V has to be dominant for it to even be any of the other two, also if the middle one isn't dominant therefore even if the third is dominant, it will be limited to the second.
Just going along with the arrows really, if it's not dominant it cannot be any of the further down the line.

I have the CGP book, but as well as the Heinemanne - I use the CGP to simplify things, like epistasis

Hi!

In primary metabolite production, why does the amount of product decrease as the population size of bacteria decreases in the death phase? Shouldn't the amount of product level off, since it's the bacteria that's dying - so how does the product get affected?

I'm referring to the top graph on pg 161 of the purple OCR A2 biology book, if you have it.

Thanks.
