Arabesque has had a previous chestnut foal (Frequent) so she must have received a chestnut gene through her dam Prophecy from Andaleeb, hidden phenotypically by the 'bay' gene (no such thing really, it's all to do with EE/AA/ee/aa but it's been a long day and I'm too tired to be genotypically accurate).  She has then passed on a chestnut gene to Showcasing along with OD's 'bay gene'.  So Showcasing looks bay but can pass on chestnut.  If he is mated to a chestnut mare there is a 75% chance of a chestnut foal, 50% when crossed to a heterozygous bay mare.

Maybe so many have been catalogued because breeders are keeping the bays and flogging the chestnuts?

Are you a Tatts employee perry? No sign of my catalogue - but hell, I'm only a vendor!

me too PotM

all it took was to put 2012 in for 2011 on the link ;-)

Thanks for the genetics stuff Jez - i had a chesnut Showcasing filly foal from a stallion who has no chesnut back to 4th generation and naturally had a bit of a head scratch working out the chances... if only i could get a yankee up with those odds...
Given the quality of chesnuts in Showcasing pedigree its no bad thing when the set foot on a racecourse but can imagine the market being a bit more challenging
Still like & positive about Showcasing but imagine it may be offputting to some

i can't seem to find that link, can you help?

Just copy and paste the link into your browser and the online pdf should appear with a to die for Mullionmileanhour filly

got it. thanks Perry

I've decided to wait before trawling through the pdf of the catalogue as I normally only cherry pick the lots online - and I go through lot by lot on paper whilst eating my porridge!

Also, I have been a bit arrested by the Mullionmileanhour filly. I must be there to try and buy her as a racing prospect

Unfortunately I suspect the vendors may blame her position in the catalogue for her being a no bid filly. Those who've been round the block a little will perhaps suspect different reasons. . .

Doesn't a hetero bay stallion throw a bay gene 50% of the time and a ches one 50% of the tome. Mated to a ches mare who provides 100% ches genes means 50% bay 50% ches.

To a hetero bay mare its then 75% bay 25% ches offspring.
