Investigating Genetic Diversity Flashcards
1
Q
How was genetic diversity investigated before gene technology was used?
A
Looking at the frequency of measurable/ observable characteristics in a population
2
Q
How does gene technology measure genetic diversity?
A
Allows DNA and mRNA sequences to be analysed directly
3
Q
Why is looking at the frequency of measurable/observable characteristics less reliable?
A
- subjective
- assumption that one characteristic is controlled by one gene
- assumption that change in characteristic is due to a change in genetics
