4.7 Investigating diversity

Question 1

Genetic diversity within, or between species, can be made by comparing:

Answer 1

the frequency of measurable or observable characteristics
the base sequence of DNA
the base sequence of mRNA
the amino acid sequence of the proteins encoded by DNA and mRNA

You should be able to appreciate that gene technology has caused a change in the methods of investigating genetic diversity; inferring DNA differences from measurable or observable characteristics has been replaced by direct investigation of DNA sequences.

Question 2

Quantitative investigations of variation within a species involve:

Answer 2

collecting data from random samples
calculating a mean value of the collected data and the standard deviation of that mean
interpreting mean values and their standard deviations
