We did not find significant differences in lifespan between purebred and mixed breed dogs; however, breeds with larger effective population sizes and/or lower inbreeding coefficients had median survival times 3-6 months longer than breeds with smaller effective population sizes or higher inbreeding coefficients, indicating that these measures ...
Chapter One traces zoological inbreeding and botanical self-fertilization in Darwin's research from his articles published in The gardeners' chronicle in the 1840s and 1850s through his The effects of cross and self fertilisation in the vegetable kingdom of 1876. In doing so, it demonstrates how Darwin metaphorically linked natural selection to ...

Inbreeding coefficients of artificially bred Ayrshire, …Inbreeding commonly leads to inbreeding depression, the reduced fitness of individuals due to deleterious recessive (or partially recessive) mutations exposed in the homozygous state [8,9]. In livestock, for every 1% increase in (pedigree-estimated) inbreeding, there is an estimated 0.13% decrease in the mean selected trait value [ 10 ].Academic inbreeding has been found to occur in all higher education systems worldwide. It has even been observed in some academic sub-disciplines in the United States and the United Kingdom, where the practice has been largely eradicated at the system level (e.g., Arismendi and Penaluna 2016).

In the western United States, pronghorn antelopes and domestic cattle often associate with one another in the same open rangeland.
