racing facts about horses with different genders with different temperament

Question
hi sir. i still remember you telling me that AGGRESSIVE FILLIES PERFORM VERY WELL IN THE RACE. it really proved. if you dont mind, can you tell me much more racing facts about fillies, mares, colts, geldings and horses with different temperament?

there is a 2 year old dark bay filly. now shes 3. trainer didnt race until she turned 3. when she was a 2 year old, she was very quiet. i still remember her being schooled. she was trotting with anxious eyes. i thought that shes really quiet, anxious. bu, as the groom changed, she turned more aggressive. never letting anyone stand near her stall. if anyone approaches her stall, she would shake her head with ears pinned, baring her teeth, charges onto us. the trainer prepared her well with one particular jockey. she impressed in the workouts. same jockey was declared to ride her in the race. she was suppose in run in 3rd race, the jockey had a fall in the 1st race on that raceday unexpectedly. the trainer was more nervous. the club declared an apprentice jockey with -3.5kg allowance to ride her. he's not only weak but also not aware of her temperament. she didnt respond in the final 2 furlongs, but what miracle happened, she picked up very quick to the final line finishing 3rd. the jockey felt took near 2 to 2.5 furlongs to halt her and turn back to paddock.

Answer
hi  each horse is like a person. no one has the same personality ,so you just have to work with each horse so you can figure them out.. if you come across a horse you cannot figure out then you should have a physic come to your barn and read your horse to let you know what the problem is so you can go from there.  thanks ED HESS
