WebReally it depends on the gene. For a particular trait, if an organism has two copies of the same allele for a given trait, it's going to pass that trait onto it's offspring. You could say a more homozygous plant would 'breed true.' Also, there's 'hybrid vigor' or Heterosis, and the opposite, inbreeding depression.
