Hi!
I don't want to heat up the moods again - I just thought one could try to give a little clarification about (what I think) offends some people in the text.
It's just the part about a DNA-strain composed by the DNA of both parents.
That information is - sorry - WRONG, and I know that some people can't stand wrong informations to be published, even in such a "small" matter.
On the other hand a genetics tutorial should be kept simple, that's right, without too much confusing infos.
A DNA-strain is (re)produced in complex mechanisms that are, here tyflier ist completely right, in no way important for understanding corn genetics.
Perhaps one could quit the whole DNA-thing and say "genetic material" or "genome"?
(That's of course only a suggestion - it's your (tyfliers) thing if your tutorial contains some tiny bits of (perhaps unimportant, but) incorrect infos as long as it helps people understand the main issue, i.e. snake genetics).
I don't think the whole "be aware! Stay away"-thing is adeqate, either - as long as everyone knows that it is a simplified tutorial.
Greetings
