3.3.2 - Measuring biodiversity within a species Flashcards
Ways to compare genetic diversity within a species.
Frequency of similar characteristics
Difference in sequence of DNA and mRNA
Amino acid sequence of proteins
What can more genetic diversity mean?
More likely to adapt to environmental change
Higher possibility that an individual possesses characteristics to survive in the new environment.
More characteristics
What is genetic diversity?
The total number of alleles in a population
Why is it better to look at DNA sequence when comparing organisms in the same species rather than looking at observable characteristics?
DNA sequence is more direct and less open to subjective interpretations.
Characteristics can be modified by the environment
What can mutations lead to?
Can increase the gene pool by increasing alleles
Advantageous alleles being passed on
