Question

Inbreeding involves the crossing of organisms that are genetically related to each other. What is a possible disadvantage of inbreeding?

Answer 1

Inbreeding compresses the gene pool, making it more likle for a genetic abbheration to occur.

Passing on negative mutations. This is seen by Cheetahs having sperm with low fertility. This was caused by nearly all of them dying out, which reduced the gene pool and meant they had to inbreed to avoid extinction.
