Inbreeding can significantly influence gene expression which can prevent inbreeding depression. There is no mechanism for preventing inbreeding or to ensure outcrossing. The reduced numbers have led to increased inbreeding and low genetic diversity. Genetic diversity in current populations is high with no signs of inbreeding. However, Alpine ibex do have low genetic diversity putting them at risk of inbreeding depression. It is geographically isolated, which can lead to inbreeding and reduced genetic diversity. Offspring of biologically related parents are subject to the possible impact of inbreeding. These transitions often occur as a result of inbreeding or mutation within large populations. Another consequence is that hymenopterans may be more resistant to the deleterious effects of inbreeding. Kin recognition thus allows avoidance of inbreeding and consequent inbreeding depression. During sexual reproduction, mating with a close relative (inbreeding) often leads to inbreeding depression. This should dramatically reduce the likelihood of inbreeding. Mortality due to infection increases significantly with increases in inbreeding. Mortality due to infection increased significantly with increases in inbreeding. The likeliest explanations are inbreeding depression or hybridity.
