Three of Lyric's puppies together from left to right
Aragon Mystic Pearl(Bryn/Pearl), Ch Aragon Aroi Silver Lining(Darby) and Ch Aragon Black Ice(Echo)
Color genetics in greyhounds is an interesting topic. Based on the color of Merlin and Lyric's puppies, Merlin was obviously homozygous for the brindle gene. Dilute or nondilute is easy to understand but the amount of brindling expressed is a mystery. For instance both Darby and Bryn/Pearl are genetically the same color-blue brindle. Darby shows much more brown than Bryn/Pearl and much less blue color ie he has less brindling. When and if bred though they both will pass on the identical color genes-Brindle and Dilute genes.
Echo is the same base color-brindle just the nondilute version.
In the next post I will go over basic color genetics in the greyhound.
