inbreeding depression
Inbreeding depression refers to the reduced biological fitness in a species resulting from mating between closely related individuals. When relatives breed, their offspring are more likely to inherit identical versions of genes, including harmful recessive traits. This can lead to a higher occurrence of genetic disorders, lower fertility, weaker immune responses, and decreased survival rates. In nature, inbreeding depression can threaten small populations where individuals are related, making it harder for them to adapt and thrive over generations. Ensuring genetic diversity is crucial for the health and resilience of a species.
