Does inbreeding cause mutations?

According to some estimates, you and I each carry about 1 strongly deleterious hidden mutation. When homozygous, these mutations reduce fitness; inbreeding will therefore lead to inbreeding depression as the homozygous mutations become expressed. However, inbreeding isn’t all bad, and many organisms habitually inbreed.

What is the most inbred country?

Is the royal family inbred?

In modern times, among European royalty at least, marriages between royal dynasties have become much rarer than they once were. This happens to avoid inbreeding, since many royal families share common ancestors, and therefore share much of the genetic pool.

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.

Does inbreeding cause mental illness?

What happens if you are inbred?

Inbreeding results in homozygosity, which can increase the chances of offspring being affected by deleterious or recessive traits. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
