Reproductive success is defined as the passing of genes onto the next generation in a way that they too can pass on those genes. In practice, this is often a tally of the number of offspring produced by an individual. A more correct definition, which incorporates inclusive fitness, is the relative production of fertile offspring by a genotype. For example, the offspring produced as a result of normal mating are an example of reproductive success, because they too can pass their genetic material on to the next generation. Alternatively, the birth of a mule as a result of the mating of a horse and a donkey is not an example of reproductive success because the mule is sterile and thus not able to continue the germ line.
Reproductive success is part of the calculation for fitness and a key element in the theories of natural selection and evolution.
Famous quotes containing the words reproductive and/or success:
“The blind conviction that we have to do something about other peoples reproductive behaviour, and that we may have to do it whether they like it or not, derives from the assumption that the world belongs to us, who have so expertly depleted its resources, rather than to them, who have not.”
—Germaine Greer (b. 1939)
“A religion so cheerless, a philosophy so sorrowful, could never have succeeded with the masses of mankind if presented only as a system of metaphysics. Buddhism owed its success to its catholic spirit and its beautiful morality.”
—W. Winwood Reade (18381875)
