4 Αυγ 2021 · Abstract. Individuals are expected to avoid mating with relatives as inbreeding can reduce offspring fitness, a phenomenon known as inbreeding depression. This has led to the widespread assumption that selection will favour individuals that avoid mating with relatives.
There is evidence that suggests inbreeding certain animals can have more of a negative impact than a positive one. The two largest populations of koalas in Australia could cease to exist by just one disease, due to them being so so heavily inbred, scientists have warned.
26 Φεβ 2015 · Natural populations of many species are faced with an increasing number of pressures from human-driven environmental changes, such as habitat degradation and fragmentation. These pressures can lead to local reductions in population size, and increases in the isolation of populations.
11 Μαΐ 2017 · Both inbreeding and inbreeding avoidance mechanisms have enormous downstream fitness consequences for cooperative breeding species. For example, they can influence reproductive dynamics leading to a monopolization of breeding opportunities by dominant individuals.
1 Μαΐ 2002 · Data from bird and mammal populations suggest that inbreeding depression often significantly affects birth weight, survival, reproduction and resistance to disease, predation and environmental stress.
INTRODUCTION. The recognition of negative effects arising in offspring of closely related parents (i.e. inbreeding depression) traces further back in history than any scientific observation of...
