His PT may be higher than his sire, but that doesn't tell you anything about where in the range of possibilities his breeding ability falls. Also the new breeding advice tests against both sire and dam. It looks like his dam is likely a very high blue (since his PT is well above the sire's AFPT). Your colt is probably a low A, so was gelded.

I agree with Ondowa in the reasoning as to why he was gelded. I think his sire was a 'low' A, and his PT and AFPT is below what the dams was. I would consider crossing your mare with stallions that have AFPT's around 11.2 or over.

I know PT does not have a correlation with breeding ability, but AFPT does show where a mare/stallion may be sitting - whether she be a 'high' or 'low' of that particular paper level.

For example, these two boys are G4 A's, PT's are 11.6 and 11.3 (Their AFPT is respectively 11.2 and 11.4). I breed them with mares with an equivalent paper level and AFPT's that are similar to or match the stallions AFPT. This season I have not yet got a snipped foal from using this method.

PT 11.6/ AFPT 11.2

IV Belle Isle

PT 11.3/ AFPT 11.4

IV Exclusively Mine

I got this intact filly from pairing Belle Isle with a mare who was Blue (PT 11.6). Her dam hadn't yet had a foal, so an AFPT was not available - I decided to breed them together as they had similar (the same!) PT.

V Enchanted Rose i8

Also the same scenario with this foal - his dam had not been bred before, so I paired her with my stallion who had a similar PT and was also on the equivalent paper level.

III Scottish Snow i8

and whats up with this foal getting altered the parents paper and AFPT were the same I'm getting so frustrated!

There's an old post from the old forum explaining some of the reasons.

Take two perfect foundations. They will have 100% breeding ability (the best for regular foundations) and a PT score of 9.9.

When they are bred together, each of them will contribute to the foal's PT score from a fairly wide range of possibilities

If the contribution from both parents comes from the top of the range, the foal will have a fairly high PT score. If both contributions come from the low end, the foal will have a low PT score. If one contribution is low and the other high, the foal will have a mid-range PT score.

This explanation is about PT score inheritance because there are lots of known numbers to help make it clear. The same sort of thing is going on with the inheritance of breeding ability, so that it is fairly common to get foals that get neutered along the way because they don't measure up to their parents.

Here is another visual, that may help (Start from the bottom):

Imagine the frustration at the level of breeding real horses! Top breeders can spend thousands of dollars and years of planning only to find mother nature (and the deities of probability) have other things in mind. I don't think any breeding program can have 100% success.

I can definitely understand how you'd be frustrated, though, if getting intact foals is what makes the game fun for you. For me, the fun is in the chance of it. Maybe I'm a closet gambler. I'd find it far less fun if I was successful every single time.

A follow up to what Waldgraf said, my mum spent a bucket load of money buying a dog in Iceland and shipping it all the way to NZ. On the way she actually thought it may have gotten lost! (In like England or something). When the dog got to Australia and the breeder there that my mum works with, it turns out this dog has an open fontanelle, meaning one bump on the head could kill it. So it's not going to go to NZ. It's been a few years since then and this dog hasn't gone into season, meaning it can't be bred from....

I learned my lesson from this that breeding isn't fun....I'm just happy about the colour combos that I get!

SandycreekFarm's explanation is not correct. There is no double random factor. Unfortunately I can't make heads of tails of that image CF posted. I don't know what it is representing.

When they are bred together, each of them will contribute a number to the foal's PT score that will range from 8.9 to 10.4. The average of these numbers will be the foal's PT score.

This is the incorrect line. :)
