4. Using Gene Technology To Assess Genetic Diversity Flashcards
Name 2 things which gene technologies have helped with ?
Clarification of evolutionary relationships.
Assessment of genetic diversity
Genetic diversity
Number of different alleles of a gene in a species or population
What were early estimates of genetic diversity
Looking at the frequency of measurable or observable characteristics in a population
Eg number of different eye colours in population and number of people with each particular eye colour
What do different allies determine ?
Different characteristics
Higher amount of characteristics the higher the genetic diversity
What do different alleles of the same gene have …
Slightly different DNA base sequences
By comparing the DNA base sequence of the same gene in different organisms in a population Allows scientists to find how many alleles of that gene there are in the population
What will different alleles alps produce …
Slightly different mRNA base sequences and in turn produce proteins with slightly different amino acid sequences - also for comparison.
