As a result, first-generation inbred individuals are more likely to show physical and health defects, including: Reduced fertility both in litter size and sperm viability. Increased genetic disorders. Fluctuating facial asymmetry. Lower birth rate. Higher infant mortality and child mortality. Smaller adult size.
What is an example of inbreeding?
Inbreeding refers to the mating of close relatives in species that are normally outbreeding. Matings between father and daughter, brother and sister, or first cousins are examples of inbreeding.
What defects are caused by inbreeding?
Inbreeding increases the risk of recessive gene disorders Inbreeding also increases the risk of disorders caused by recessive genes. These disorders can lead to calf abnormalities, miscarriages and stillbirths. Animals must have two copies of a recessive gene to have the disorder.

Are blue eyes caused by inbreeding?
However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.
Are all humans inbred?
Since we are all humans and all share a common ancestor somewhere down the line, we all have some degree of inbreeding. Some research shows that the whole human race was down to a few thousand people around 70,000 years ago. Of course, a small population isn’t the only reason for inbreeding.
Are blue eyes an indication of inbreeding?
Blue eyes are a recessive trait, and the gene must be inherited from both parents. (Green eyes involve a related but different gene, one that is recessive to brown but dominant to blue.)Feb 1, 2008.

The results suggest that people deliberately sought partners beyond their immediate family, and that they were probably connected to a wider network of groups from within which mates were chosen, in order to avoid becoming inbred.
Is there inbreeding in nature?
A new meta-analysis in Nature Ecology & Evolution has found that on the whole, animals – even humans – don’t avoid inbreeding. The paper examined 139 studies across 88 species, finding that animals rarely avoided mating with relatives.
Who are we most related to?
It confirms that our closest living biological relatives are chimpanzees and bonobos, with whom we share many traits. But we did not evolve directly from any primates living today. DNA also shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago.
