Which of the following is true about inbreeding?

Question

It causes increased fertility in offspring.

It causes faster growth rates.

It causes elevated incidence of recessive genetic diseases.

It decreases the frequency of detrimental rare variants, leading to better population health.

Answer 1

The statement that is true about inbreeding is:

It causes elevated incidence of recessive genetic diseases.

Inbreeding increases the likelihood that offspring will inherit the same alleles from both parents, especially when those alleles are recessive. This can lead to a higher incidence of genetic disorders that are carried by recessive alleles. The other statements about inbreeding leading to increased fertility, faster growth rates, or better population health are generally not accurate.
