'''Outbreeding depression''' is a decrease in an organism's ability to survive and [[reproductive success|reproduce]] due to
breeding between different races. Generating intermediate genotypes that are less fit than either parent as well as a breakdown of biochemical or physiological compatibility. For example, selection in one population might favor a large body size, whereas in another population small body size might be more advantageous, while individuals with intermediate body sizes are often disadvantaged in both populations.<ref>https://en.wikipedia.org/wiki/Outbreeding_depression</ref>
