How is the viability of offspring affected by interbreeding within a species?

Interbreeding within a species can have significant effects on the genetic health of the offspring. In particular, while the selected answer suggests that interbreeding increases the chances of viability, it is essential to recognize the context of genetic diversity. Interbreeding often leads to a reduction in genetic diversity, especially if it occurs within a small, isolated population. This lack of diversity can result in a higher prevalence of recessive genetic disorders and reduced overall fitness.

Conversely, when interbreeding is managed with a focus on maintaining genetic diversity, it can preserve essential adaptations and overall health within the species. However, if the interbreeding in question reflects breeding between genetically similar individuals or populations, it can promote genetic problems such as inbreeding depression, affecting viability unfavorably. Therefore, while the answer proposes an increase in viability, it doesn’t take into account the critical aspect of genetic health that interbreeding often compromises, leading to the conclusion that interbreeding can generally diminish the viability of offspring due to growing genetic vulnerabilities.
