Answers about horse cloning

Coat colour of the foal

Pieraz is a grey gelding, and the resulting clone, Pieraz-Cryozootech-Stallion is described as a brown foal with a small white star. Could you please tell me how the colour change came about ? ( I.H. )
Pieraz Cryozootech-Stallion is the clone of PIERAZ, a grey gelding. Pieraz Cryozootech-Stallion will be grey when adult, but as a baby he has a bay coat. Young foals never show grey hair at birth, and they become gray only progressively to and almost white when being old.

Genes transmission

How will you know that this horse has the same heart and drive to compete that Pieraz had ? (L.R.)
This horse is not made for performing but for transmitting the genes of PIERAZ to future generations of performers. For this purpose one can be affirmative: he will transmit exactly the same genes as PIERAZ would have, if he had not been castrated.

Surrogate mare

I wonder about the ’surrogate’ brood mare for Pieraz Cryozootech-Stallion. If you used a Clydsedale mare, would the foal be larger and stronger at birth ? (N. California)
With a Clydsedale mare as recipient mare, the foal would probably be stronger at birth. However, it is not a better option as the foal gets large quantity of very rich milk, and can be overweight. Anyway, Pieraz Cryozootech-Stallion is to be a stallion, so whatever is the birth weight, the genetic delivered by his spermatozoa will be the same.
