Outbreeding depression: Difference between revisions

'''Outbreeding depression''' is a decrease in an organism's ability to survive and [[reproductive success|reproduce]] due to breeding across 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>  

The science is uncertain and incomplete, so all of this ought to be taken with a grain of salt. Any effects observed could stem from identity and integration issues and also selection bias due to the type of people who may be more prone to engaging in miscegenation.
