Hey there! Let's have some fun with genetics and horses!
When a palomino stud (eecr) is bred to a palomino mare, both of whom are Quarter horses, we can use a Punnett square to determine the possible genotypes of their offspring.
In this case, since both the stud and the mare are palomino, their genotypes would be eecr.
Now, let's complete the Punnett square:
e e c r
--------------
e | ee ee ec er
e | ee ee ec er
c | ec ec ecre ecr
r | er er ecr ecr
From the Punnett square, we can see the possible genotypes:
Black (EE): 0%
Red (ee): 0%
Palomino (ecre or eecr): 100%
Cremello (ecrecr): 0%
So, when crossing the palomino stud with the palomino mare, the genotype results would be 100% Palomino.
Hope that helps! If you have any more questions or if there's anything else you'd like to know, feel free to ask!
