It’s a plus-plus, also known as mutualistic relationship. Our intestines provide a habitat for the good bacteria and in return the bacteria fend off bad bacteria from harming us.
If I am not wrong, I think you may have forgotten to add the rest of the question!
Answer:
Inbreeding and greater chance of passing deletereous mutations through generations
Explanation:
There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding
, that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.
On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.
