WebBiology; Biology questions and answers; If the frequency of the A allele is 0.7 and the frequency of the a allele is 0.3 given the fitness values for the various genotypes what is the mean fitness of the population? Fitness values AA 1.0 Aa 0.4 aa 0.1 WebNov 7, 2024 · The test statistic for a goodness-of-fit test is: ∑ k (O − E)2 E. where: O = observed values (data) E = expected values (from theory) k = the number of different data cells or categories. The observed values are the data values and the expected values are the values you would expect to get if the null hypothesis were true.

Fitness (often denoted $${\displaystyle w}$$ or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be … See more Fitness is often defined as a propensity or probability, rather than the actual number of offspring. For example, according to Maynard Smith, "Fitness is a property, not of an individual, but of a class of individuals—for … See more In order to avoid the complications of sex and recombination, the concept of fitness is restricted to an asexual population without genetic recombination.
