Classical studies of inbreeding in laboratory animals and livestock have shown that increased homozygosity can adversely affect spermatogenesis, ovulation and perinatal mortality and morbidity 1–3.

2024年7月11日 · Inbreeding Depression in the African Lion. The risk of inbreeding within fragmented lion populations is a fundamental problem in conservation biology and although the problem has been clearly established, its impact has been greatly underestimated.

2021年2月14日 · It is true that African lions have recently become more prone to inbreeding, largely due to human actions (reasons include limited dispersal and at least temporarily reduced pride sizes). see here. Generally though, lions likely avoid mating with close relatives innately as most animal species do. see e.g. here

2025年3月12日 · Lions live in complex social groups that influence their genetic diversity. While inbreeding is a concern for many species with small or isolated populations, lions have evolved behaviors to mitigate its risks. However, under certain conditions, inbreeding can still occur, leading to potential consequences for their health and survival.

2022年1月1日 · Our study provides the first physical evidence that mountain lions in Southern California are experiencing inbreeding depression, leading to reduced fitness because of lower survival, mating, or reproduction [20]. Here we present nine individuals exhibiting physical (phenotypical) signs of inbreeding depression in Southern California.

2 天之前 · The "shock" birth of three lion cubs in captivity was the result of an incestuous mating between a mother and her son, it has been revealed. The Yorkshire Wildlife Park (YWP) rescued a family of ...

2025年3月24日 · Inbreeding Among Lions. In the animal kingdom, inbreeding – the practice of mating between close relatives – occurs under certain circumstances, and lions, despite their complex social structures, are not exempt from this phenomenon.

We confirmed that the loss of allelic richness (probably resulting from genetic drift and small number of founders) has resulted in low genetic diversity and inbreeding. The SVC lion population was also found to be genetically differentiated from surrounding population, as a result of genetic drift and restricted natural dispersal due to ...

Inbreeding within fragmented lion populations is a significant issue in conservation biology. Inbreeding can lead to reduced genetic variation, low reproductive performance, increased cub mortality, and reduced immune competence. To avoid inbreeding depression, a lion population needs to have at least 50 prides with no limits to dispersal.

2025年3月20日 · The short answer is yes, lions do sometimes inbreed, though it’s not their preferred reproductive strategy. While natural mechanisms and behaviors exist to minimize it, inbreeding within lion populations is a real and documented phenomenon.
