Introduction. Inbreeding refers to the production of offspring by the mating of related individuals, often via consanguinity—intra-familial unions of individuals related as second cousins or closer.

Lush was a student of Sewall Wright, who devised the coefficient of inbreeding, and a background in both genetics and mathematics allowed him to develop animal breeding into a quantitative science.With data on the effects of inbreeding in wild populations scarce, some zoologists questioned its importance (or even its existence) in natural populations 1, 2, 3. Recent evidence, however, now suggests that both inbreeding and inbreeding depression are more pervasive than previously realized.Estimates of lethal equivalents are significantly greater under stressful (mean=1.45, median=1.02) than relatively benign (mean=0.85, median=0.61) conditions.
