WebDec 20, 2024 · Inbreeding depression is the reduction in fitness and vigor resulting from mating of close relatives observed in many plant and animal species. Mating of close relatives increases the probability that an individual inherits two non-functioning mutations at the same gene, resulting in lower fitness of such matings. 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.
