2. The inbreeding of the royal family led to a high rate of genetic disorders within the royal family.
3. The small population of the species was inbred and this led to the extinction of the species.
4. Inbreeding leads to the expression of deleterious recessive alleles which in turn leads to reduced fertility and increased mortality.
5. The inbreeding of the species led to a decrease in genetic diversity and an increase in genetic disorders.
