Homozygous (or Purebred) - The genotype for the characteristic has the same genes/alleles (e.g. BB, bb). Heterozygous (or Hybrid) - The genotype for the characteristic has different genes/alleles (e.g. Bb). Wild-type - The most common phenotypes in a population are called the wild-type.
Mixed breeds. Mixed-breed dogs live an average of 14 years. Overall, purebreds live an average of nearly 10 years. The difference may be because dogs bred to meet standards sometimes pass along problems in their genes, too. Itâs hard to predict how long a mixed-breed dog will live, but your mutt is certain to be one-of-a-kind and probably a lot less expensive!
