It depends on what you mean by "better" in relationship to the foal.

Showing ability, as reflected by a horse's PT score is entirely separate from breeding ability. If a foal's PT score is higher than its sire's or dam's, that means that it is better at showing than the parent whose PT score it exceeds. Note that if you breed two perfect foundations (with PT scores of 9.9) to each other, the PT scores of their foals can range anywhere from 8.9 to 10.4.

However, if you are interested in how the foal compares to its parents as a breeder, you have to look at other tests. Colts that are significantly worse than their sires for breeding will be neutered by Gelding Advice. Fillies that are significantly worse than their dams for breeding will be neutered by Strict Mare Advice. Regular Mare advice lets more fillies pass without being neutered. Stallion papering will let you know how a colt papers, so you can compare the results of that test for sire and son to see if the son is better. The Comparison Test, if you can afford it, will give you an even more exact comparison of son and sire, or two brothers, or two totally unrelated stallions, as well, as long as you own both horses to be compared.

Since a mare has to have at least 3 "live" offspring before she can be papered, it takes a lot longer to compare a filly's paper level with her dam's.

Another way to compare the breeding ability of two horses is to check their Average Foal PT, or AFPT. I think having this calculated and reported on the Family tab is a perk of the Premium Upgrade, but it is possible to do it manually by totaling the PT score's of a horse's foals and dividing by the number of PT tested foals in the record. Note that the more foals a horse has, the more accurate a gauge this statistic provides. In the automatic calculation, only offspring that have been PT tested are included (as is the case for doing it on your own, of course).
