Good stuff Y.A.! Now, did you notice the column that said "sex chromosome mechanism in the male"? It was XO instead of the familiar XY. Does that suggest diploidy or haploidy to you (easy one!) and what is the mechanism used to explain the loss of the Y chromosome (much harder. It has the word "fusion" in it)?

Enjoy

well it's interesting stuff OP (Old phil), i think they have 3 sex chromosomes

i do know in insects males r XX and femmes r XY (at least in lepidoptera)

Sex chromosomes are not exclusively XX XY, birds have ZY chromosomes

Read up on it here if you are interested

Sigh... Wikipedia referencing is bad I know, but the info is so good most of the time

Sounds good mate, I'm studying it at uni so a bit of revision for high school, first and second year stuff would be nice.

Im in AP Biology this year genetics are wonderful, you'll learn more about mitosis/miosis and the genome than you'll have ever dreamed. (and much much more)... For AP Bio I've been wanting to do a research paper on mantids, but dont know what to do it on... :/

use a practical species

i would obtain sphodromantis or something and rear groups of nymphs in different conditions and measure mortality rate

use something easy, fast growing, and with low mortality
