If they are seedless, how the hell do they make the seeds to plant them?
"All truths are easy to understand once they are discovered; the point is to discover them."

They have one normal that makes a gazillion seedless?
I think they are made with normal watermellons, then they are stopped growing their own seeds through certain processes, like chemicals and stopping the plant from becoming polinised.
It's a little complex, but they're triploid plants, meaning instead of having a pair of each chromosome they have three, so that meiosis (part of cell division) doesn't take place, which in turn means no gametes (the sperm and egg for fruits, aka the seed) can form, and voila, no seeds.
Biology.
edit: oh right, I didnt' answer your question haha. Well in the case of watermelons, simply put they get 4-ploid (can't remember the name tetra or quadi) watermelons (four of each chromosome), cross breed them with your normal diploids, and in a much more deep process that will take too much for me to remember, create seeds that are triploid.
seedless oranges are much easier to explain. they just make grafted clones. heh.

*having a headache..* too many difficult words..
wow. i actually understood you, sleeping in the 1st quarter of bio and actually paying attention in 2nd quarter paid off.
hah amazing. its always cool to understand gibberish. makes you feel sophisticated. makes me feel sophisticated when I laugh at british comedy too.
Ivf
all i heard was watermealons and biology

Diploid is a funny word!
Dumb question, but can you eat the seeds in watermellons??, i always scoop them out and throw em coz im sure i was told they make you ill or something!
GM watermelons?
I eat the seeds because I'm too lazy to take them out.
I'm fine.
I'm fine.
They're fine. but eating the black seeds takes away from the pleasure of eating a soft... mushy... mess...
...
Why do "I" like watermelons? *boggled*

Good to know, now i won't try scooping every last tiny one out like they're scary poisonous things.
Seedless watermelon never taste as good as the regular stuff.
I was with you right up until "Little", after that you lost me.Coolbeano wrote:
