Investigating Diversity Flashcards
1
Q
4 ways we can compare genetic diversity
A
- frequency of observable characteristics
- base sequence of DNA
- base sequence of mRNA
- amino acid sequence
2
Q
What is meant by Gene technology
A
- sampling DNA or mRNA in order to read and compare the base sequence of organism
- the amino acid sequence can be studied as this will also provide information on the organisms mRNA and DNA sequences
3
Q
Why do scientist prefer to use gene technology instead of observations
A
- not reliable characteristics could be coded for by more than on gene or could be influenced by the environment
4
Q
Interspecific variation
A
Differences between individuals of different species
5
Q
Intraspecific variation
A
Differences between individuals of the same species
6
Q
What is sampling
A
Selecting a group of individuals to measure that will represent the whole target population
7
Q
How can a random sample be achieved
A
Create a grid for your sample area, and then randomly generate coordinates where a quadrat or transect can be placed repeat until required sample size is reached
