Inbreeding can sometimes lead to homozygous

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

Inbreeding strongly increases overall homozygosity which subjects inbred individuals to diseases caused by rare recessive alleles.
