RE: Left arm vs. right arm blood pressure question 9/16/2005 5:01AM - in reply to veryyyy. Reply. Return to Index. Report Post. The plumbing from the heart to the left arm is more direct than to the right arm, so in order to get truer numbers, the left arm is preferred.
Pedigrees show how characteristics are passed from one generation to the next. They are used in studying human genetics because it is not possible to carry out controlleâ¦d breeding experiments with humans, as we can with other animals or with plants.
So why bother with a pedigree if you're looking for a pet, not a show or breeding dog? For several reasons. First, the pedigree gives you an indication of whether the breeder is a serious, responsible breeder of quality dogs, or just a puppy producer trying to make a buck. How can you, a novice in the world of canine pedigrees, tell the difference?
