Thirteen, what fascinating photo capture of your beautiful horse, Holly's transitions! Thank you for sharing this. I am just now beginning to teach myself of the genetics of horse coloring, and I find it absolutely engaging.
As well, Soenjer, your Envi is stunning! Her transitions are awesome also.
I read that with Grays, who are the general initiating color for all eventual white horses (in most cases, anyway, per my reading; is that correct?) there is, very sadly, a 70-80% chance of them developing, by about age 15, a NON-malignant form of melanoma, which is curable, and at times may return as a malignant, organ-based carcinoma.
Has this been either of your experiences, owning or working with Grays previously? Does this seem accurate to you?
I found it disappointing and sad, to say the least, and also confusing. Disappointing because, though color is far down on my list of importance when choosing my eventual horse, I would find owning a grey (or one who had turned nearly all white if I bought an older horse beyond the age of eight at which time they have usually completely grayed, per this researcher's commentary, which is likely for my needs) to be a great bonus.
I find the info sad for obvious reasons, but also very curious. If this IS TRUE, then on average, there is the likelihood that approximately only 20-30% of grey/white horses would live well into old age, at least without significant illness/treatment for such being necessary art some point. I would imagine that would be a reason for many breeders and horse owners to avoid this color choice when deciding on their animal?
Any input would be greatly interesting...this particular information was found on a site which Chiilaa had posted for genetic color testing...I printed out all of the information the site provided on basic color facts and homo/heterozygous traits, along with genetic anomalies which breeders screen for and why...I do hope I have properly restated this info which I read re: Grays/cancers...if not, I will reread and quote directly as not to misinform others!
Thank you again for your photos! Any input on the other issues would be wonderful! :0)
