Inbreeding depression in male gametic performance
Journal of Evolutionary Biology, 2014AbstractOne key objective in evolutionary ecology is to understand the magnitude of inbreeding depression expressed across sex‐specific components of fitness. One major component of male fitness is fertilization success, which depends on male gametic performance (sperm and pollen performance in animals and plants, respectively).

Inbreeding Depression and Heterosis
The assessments of heterosis and inbreeding depression together provide information about the gene action involved in the expression of different polygynous traits, hence for plant breeders. Knowledge of hybrid vigour and inbreeding decline is essential.1Dr. Prem Kumar, Gautam +1 more

Inbreeding and inbreeding depression in Irish Holstein-Friesian cattle
Proceedings of the British Society of Animal Science, 2007Inbreeding occurs when related individuals are mated to each other. Inbreeding reduces milk production, and impairs health, fertility and survival; a phenomenon known as inbreeding depression. Smith et al. (1998) reported losses in milk yield of 27 kg per 1% increase in inbreeding in US Holsteins.

Inbreeding and outbreeding depression in Daphnia
Oecologia, 1993Egg-to-adult viability of sexual offspring in Daphnia magna is lower for selfed (average: 43.0%) than for outcrossed families (average: 74.7%). This suggests that intraclonal mating is not the rule in Daphnia populations. For a given family, hatching rate of eggs resulting from interpopulation crosses is lower than for intrapopulation crosses.
