Why Was Elspeth Not Born White ?
« on: 26/09/2008 21:56:10 »
Dear Horseologists and people with sore throats affecting their vocal chords !

see Elspeth here ?




She's a fine looking filly isn't she ?

As far as horseys goes, she's a babe !....I'm a sheep...give me some steps and I'll do her !!


..However, I discovered something fascinating today. I heard that white horseys are not born white !...and that in fact the whiteness comes many years later ! [:0]

Why's that then ?..why was Elspeth not born white ?..what colour was she when she was born ?

I just don't know...I'm sitting here beside myself paralysed and entranced with the awe and wonder of what the answer must be !

Can ewe help release me ?

Thanking ewe



hugs and shmishes


Neil

There is a difference between white and grey horses. Most horses that you would call white are actually grey.

Greys have black skin & dark eyes. White horses are quite rare and have pink skin with, usually, blue eyes.

Greys are born either bay or black (black being quite rare) and turn lighter each year as the greying increases. It takes 6-10 years for the greying to complete. Whites, on the other hand, are born white.

Pure white horses are rarer due to genetics. The 'W' gene is recessive. There are also genetic problems such as what is known as "Lethal White". That can occur when a horse has either "WW" or "OO" gene combinations. But I won't go into the complexities of equine colour genetics as it's a very complicated affair. However, if you wish to know more, I shall happily elucidate for your benefit  :)

That is correct Nielep, pure whites are born white. Most white horses you see are old nags. Their backs also start to sag with age too.
