The answer is no, high biological fitness in one environment doesn’t have to be high in another environment.
Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. Fitness depends on environment so it changes if the environment changes. The fitness of a genotype is manifested through its phenotype, which is affected by the environment.
Answer: False.
Genetic drift is a stochastic process that occurs randomly through time. It refers to random fluctuations in allele frequencies due to chance events (small population size).
Explanation: Factors that can affect genetic diversity are Genetic drift, mutation, selection, migration, non-random mating and recombination.
Of these factors, forces that majorly control the fate of genetic variation in populations are genetic drift and natural selection.
Genetic drift refers to random fluctuations in allele frequencies due to chance events (small population size).
Natural selection involves environmental conditions acting on wild plant or animal populations or species. Most fit in a selection refers to genotype or phenotype with greater average reproductive output over it's lifespan than other genotypes or phenotypes.
