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 ...

  • Genetic / Evolution Results

    Those less fit must be assigned a fitness of less than 1. The difference between 1 and the fitness value is called the selection coefficient. The relationship between fitness, W, and the selection coefficient, s, is given by the equation, W = 1-s.

  • Mathematical problems in genetics and natural selection

    The selection coefficient (s) for the tan rabbits, using s = 1 - w, is then s = 1 - 0.91 or s = 0.09 [which you were already given, but I'm sure that you are expected to know how to calculate it as well].

  • Evolution explained in this solution

    Natural selection is not only known mechanism which drives evolution. Other mechanisms include genetic drift, sexual selection, artificial selection, group selection (inclusive fitness) and the neutral theory.

    The t test suggests that all independent variables except weight have significant regression coefficient at 0.05 significance level. The model adequacy is evaluated using the coefficient of determination R2. Here R2 =0.848.

  • fitness value

    Because of fitness (i.e. natural selection), p and q will constantly change, favoring the allele with a better fitness. Eventually, at least theoretically, after an infinite number of generations, the lower fitness valued allele would disappear.
