The coefficient for selection between Zid+ and Zid- in common garden experiment of an individual being treated with AZT is 0.036, indicating selection for Zid-.
What are the relative fitnesses of Zid- and Zid+?
Absolute fitness of Zid+ in AZT treated people is 1.040. What's the Absolute fitness for Zid-?
Note: Formatted response is also attached as a pdf document.
Fitness is an indicator of the rate of growth of a given genotype within a population. Absolute fitness (wabsolute) is a ratio of the number of individuals with a particular genotype in a given generation divided by the number of individuals with that genotype in the previous generation.
wabsolute of genotype A = Number in generation n / Number in generation n-1
Number indicates the number of individuals with genotype A in the given generations.
Relative fitness (wrelative) is the ratio of the absolute fitness of a given genotype divided by the absolute fitness of the most fit genotype. The relative fitness of the most fit genotype would ...
Relative fitness and absolute fitness using selection coefficients are examined.
