Species with low genetic diversity are at risk of decline or extinction because:

• they have a higher chance of disease susceptibility.

• they can easily adapt to environmental changes.

• they have a large population size.

• they have a wide range of genetic traits.

• Genetic management

• Public awareness campaigns

• Dietary changes

Why is genetic diversity within a population important?

• So the population is less susceptible to disease

• So individuals of the population can survive when the environment changes

• So museums can have more realistic collections

• Both A and B are correct.
