Send Frankel to Kind ?

Roadrunner, I'm not sure this is the right game for you. I don't call mating with your mother a "slightly close relationship".

Been tried with other horses centuries back.  Couldn't run a yard.

Not much difference to covering a daughter, one of those has been on the racecourse in the last 10 years but I cant remember their name, sorry.

slighty close relationship?

roadrunner46?  or same line?

Say its the same breeding alright RA, same sire who was probably also his uncle!!

at the end of the day, 99% of the breed are descended from 3 thoroughbreds, so it's all a bit royal family anyway. Must happen in the wild all the time, you can't tell me that when a lion or something fancies a bit he always waits for the missus to come home ?

Some breeds are renowned for close breeding - Welsh Cobs and ponies, and some sectors of Arabian breeding.  Look at the pedigree of this champion show Arabian and note how many times Precious As Gold appears in the third generation: http://www.allbreedpedigree.com/index.php?query_type=horse&h=VIVEGAS&g=5&cellpadding=0&small_font=1&l=

When it works it's linebreeding, when it doesn't it's inbreeding

Juddmonte have bred half brother/sister together before. Stiletta and Warning were both out of Slightly Dangerous and bred Atelier together. As far as I am aware the horse never ran so the experiement wasnt that successful.
