Chances of getting a grey?

[Jenny]

If you breed mares to a grey stallion, like bays, chestnuts etc. What are the chances you get a grey? is it 50%.
I have always said I have fields of brown horses I need some greys!!! But sadly all my mares are bays.
But there is hope with the new stud of adding some colour!!!

Depends on the parents. With Judith's Wild Rush it will be 50/50 as he has one non-grey parent.

Yes, it depends on the gray's parents. If one of them was not gray then you have a 50% chance. If both of them were gray then the stallion has a 33% chance of being homozygous and thus producing 100% grays. There are a few existing homozygous grays out there if I'm not mistaken.

thanks guys. I will take my 50% and run with it.

For what it's worth, I have a black mare...bred 3 times to the same grey...FIRST one GREY, 2nd and 3rd bay with a few white hairs throughout their coats...

GOOD LUCK

****EDIT to say and ASK.....I GUESS "Isaiah" only had one parent grey...His Sire is grey...NOW....my one bay filly....grey dad with one grey parent....and black mom no greys...has ????? % of throwing a grey????****

Apropos this topic.

Let's see if this one is homozygous gray. Haven't heard anything about his progeny.

I always thought that gray was a straight simple dominant. So of both gray parents have a non-gray parent (each would carry only one copy of the gray gene) then they would produce the following results

1:2:1,

1 GG Dominant Gray no chance of producing a non-gray
2 Gg Gray, 50% chance of gray, 50% chance of non-gray
1 gg non-gray, does not carry the gene.

Which would put the chance of getting a Dominant gray as 25%.
Regular gray 50%
Non-gray 25%

So breeding to a Dominant gray, all foals would be gray.
Breeding to a regular (one copy) gray, 50%-50%
Non-gray to non-gray, always non-gray.



Works the same way as cream except you can see the double dilutes.

One cream = palomino/buckskin/smokey black
Two cream = cremello/perlino/smokey cream.

Much easier to work with when you can see the genes at work.

hummm; Bay mares bred to cremellos can produce palominos and buckskins... Though not likely going to be the fastest race horses.

Other are correct. If the stallion onyl carrier one grey gene then you have a 50% chance. If the stallion carries two grey genes then you will be at 100%. Good luck going grey...

The probability of getting a grey is inversely proportional to your desire for one. I adore greys. I bred 4 mares to a grey. I got one.
