<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
