I have a small question regarding this screen.

Say, If I trade one of my technologies for someone else's then does that mean I wont be able to use the technology I invented and traded. For example, I have ion drive engines researched and trade it with the altarians for beam technology, so does that mean I wont be able to put ion drives on my ship until I research that technology again?

I know its a stupid question but im kinda new to GalCiv universe

Thanks
