3.3.2 - Measuring biodiversity within a species

Question 1

Ways to compare genetic diversity within a species.

Answer 1

Frequency of similar characteristics
Difference in sequence of DNA and mRNA
Amino acid sequence of proteins

Question 2

What can more genetic diversity mean?

Answer 2

More likely to adapt to environmental change
Higher possibility that an individual possesses characteristics to survive in the new environment.
More characteristics

Question 3

What is genetic diversity?

Answer 3

The total number of alleles in a population

Question 4

Why is it better to look at DNA sequence when comparing organisms in the same species rather than looking at observable characteristics?

Answer 4

DNA sequence is more direct and less open to subjective interpretations.
Characteristics can be modified by the environment

Question 5

What can mutations lead to?

Answer 5

Can increase the gene pool by increasing alleles
Advantageous alleles being passed on
