It’s not the Wahlund effect, but Sewall Wright developed F-statistics while studying this phenomenon within cattle populations. Over time, this phenomenon reestablishes mutation-selection equilibrium through genetic purging. It’s not genetic drift nor speciation, but in extinction vortex diagrams, this phenomenon occurs after reductions in effective population size and population fragmentation. The increase in the frequency of (*) homozygous alleles due to this phenomenon leads to a decrease in fitness called its namesake depression. Royal diseases such as prognathism and hemophilia are consequences of this phenomenon observed during the intermarriage of royal families. For 10 points, identify this kind of mating between two genetically related parents. ■END■
ANSWER: inbreeding [accept incest; accept full-sib mating; accept heterozygosity before “mutation-selection” is read and reject afterward; prompt on fertilization or reproduction or pollination or mating or breeding before mating; reject “interbreeding” or “outbreeding” or “crossbreeding” or “outcrossing”]
