In what forms can variation within a species exist?
i) environmental ii) genetic iii) a combination of both
1 of 7
Define mutation.
A rare, random change in genetic material that can be inherited.
2 of 7
Define evolution.
By means of natural selection - survival of the fittest.
3 of 7
Define resistance to antibiotics.
This can increase bacterial population.
4 of 7
Are mutations harmful, neutral or beneficial?
Many mutations are harmful. Some mutations are neutral. A few mutations are beneficial.
5 of 7
What increases the incidence of mutations?
Exposure to ionising radiation and some chemical mutations.
6 of 7
Why does selective breeding exist?
Desired genetic characteristics can be passed on, creating stronger, better & more profitable offspring.
