Genetics & Reproduction How can reduced genetic variation affect reproductive success in selectively bred populations? February 9, 2026 by Riding Reduced genetic variation in selectively bred populations can lead to decreased reproductive success due to increased susceptibility to diseases and environmental changes. This reduction in genetic diversity limits the ability of populations to adapt to new challenges, potentially leading to inbreeding depression and reduced overall fitness. What is Genetic Variation and Why is it Important? […] Read more »
