Comment on How many people would a generation ship need to have for inbreeding to not be an issue?

Around 4000.

When inbreeding effects are included, estimates of MVP for many species are in the thousands. Based on a meta-analysis of reported values in the literature for many species, Traill et al. reported concerning vertebrates “a cross-species frequency distribution of MVP with a median of 4169 individuals (95% CI = 3577–5129).”[8]

As I understand the article, it relates to the wild conditions. There is some evidence of lucky population that can survive after only 20 human bottleneck - en.wikipedia.org/wiki/Pingelap. And humanity itself could have faced of around 1000 spices bottleneck - en.wikipedia.org/wiki/Population_bottleneck.

That does not apply to humans who are capable of intentionally avoiding certain breeding problems, and also who have medical knowledge that can apply even if it does happen.
