Question

What is a potential problem with inbreeding?

Answer 1

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

Answer 2

Inbreeding reduces genetic diversity (which reduces variation and evolutionary potential), and dramatically increases the chances of disorders. It can also be fatal.
