The new scientific understanding of color pigmentation of hair can bu used to ensure us better Yorkies. It must be realized that we can no longer think only in terms of Mendelian genetics, where we have simple dominant and recessive effects governing the development of a trait. We are dealing multiple genes affecting the hairs coloration, each pair of genes (alleles) contribute to the desired trait. Each has a recessive and dominant form, but it is the number of gene pairs and their independent behavior from the other contributing genes during the process of recombination at fretilization that makes for the attainment of the Yorkies' desired prime important points of coat color and texture. end quote
excuse mistakes I was typing fast to get this in one post |
Yeah, I agree but don't understand WHY so many don't seem to UNDERSTAND or Get it?
In the old days before genetics was understood, I can see where a pup of a different color, was thought to resulted from breeding to the wrong stud, thus culling the pup or the litter. Problem was, Mom carried the gene too, so where did she get it from?
