Weight on back foot

I used to play baseball and ever since I have taken up golf something that I find myself doing frequently is keeping my weight on my back foot instead of following through on my front foot. Could this be the cause of a bad slice that I sometimes hit off the tee? What other negatives might there be because of keeping my weight on my back foot?

slice?  yes

plus many other problems.

Transferring your weight forward is one of the most fundamental and necessary parts of the golf swing.

Other negatives per my experience: you fall back, hit a very high up swing and hitting it fat.

I would agree with everyone else. Its one of, if not the most important fundamental in golf.  This is how you keep your balance, and if your off balance then your shots can be all over the place.  Slice is very typical, and honestly from that position the ball can go anywhere...so you will never learn from your shots, which is how you teach yourself to play golf. Also understand that your equipment will effect where the ball goes...so don't learn how to golf by watching the ball flight of ill fitted clubs. Make sure you have the correct lie and loft on your irons, and that your giving yourself enough loft on your woods to succeed.

don't you have to transfer the weight to the front foot in baseball as well?

I hit a nasty slice with only my driver, I hit a nice fade with my irons and 3 wood but when it comes to the driver, ugh..lol. I know what my issues are, just working them out and one of them is not always getting my weight transferred. If I don't get it transferred as I need to it will go as high as my pitching wedge if not higher and slice HARD. So yes, not shifting you weight can be one of the causes amongst other things.
