Serious breeding question

[Sweet Louis]

I learned how to read a program at 10..I'm 50 now so I've been around this sport a long time....now yes I'm quite aware of breeding but what makes a horse like Sweet Lou produce so many good filly offspring but not so much on the colt side..is It a luck of the draw or is there really a factor here.

[RANDOLPH POKER]

8 of his 10 richest, and 9 of his 10 fastest, are males.

He does seem to have a bunch of good fillies this year....but some decent colts too.

6 $100K winning 2YOs this year - 3 males

He does have a Horse of the Year and a few Jug Winners....not too shabby...
