Inbreeding and outbreeding depression in natural populations of Chamaecrista fasciculata (fabaceae)

Article Abstract:

The consequences of restoring heterozygosity and hence the fitness of inbred populations of Chamaecrista fasciculata are examined by conducting interpopulation crosses and measuring the performance of later generation hybrids under field conditions. Crossing populations up to intermediate distances of hundreds of kilometers has a short-term beneficial effect on progeny performance, and long-term effects are not necessarily disruptive of fitness, at least relative to parental performance.

Increased Infectious Disease Susceptibility Resulting from Outbreeding Depression

Article Abstract:

Studies of largemouth bass demonstrate that hybrid species can possess a higher level of susceptibility to infectious diseases, due to coadapted gene complex disruptions within the outbred fish immune systems.

Modeling factors affecting the severity of outbreeding depression

Article Abstract:

Research has been conducted on hybridization between populations. The hypothesis that this hybridization may cause increased fitness or decreased fitness has been tested, and the results are reported.
