Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths.

Myofibrils are the building blocks or contractile unit of each muscle fiber. The tiniest functional unit of skeletal muscle, the sarcomere, is found in the myofibrils and is made up of protein filaments: actin (thin) and myosin (thick).
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.
