The analysis of sapphire (ppaa) younger animals portion in offspring of silver-blue females heterozygous by Aleutian gene (ppAa) was carried out depending on birth liner quantity, pregnancy duration and date of puppy birth. The portion of sapphire puppies in mixed litter was found to correlate with the birth litter Quantity and date of birth. The conclusion was drawn the selective sapphire embryos elimination to be connected with blastocyst implantation.
