Top best answers to the question «Genetic drift will always lead to higher fitness»
- Genetic drift also has two significant longer-term evolutionary consequences. Genetic drift can facilitate speciation (creation of a new species) by allowing the accumulation of non-adaptive mutations that can facilitate population subdivision. Drift also facilitates the movement of a population from a lower fitness plateau to a higher fitness plateau according to the shifting balance theory of Sewall Wright.

He suggested that in moderate-size populations drift would act to change allele frequencies in a direction that might not be favored by natural selection but could allow the population to explore the fitness landscape and possibly evolve to a higher fitness plateau.
When homozygous, these mutations reduce fitness; inbreeding will therefore lead to inbreeding depression as the homozygous mutations become expressed. However, inbreeding isn't all bad, and many organisms habitually inbreed.

Ester1 higher fitness on coast; away from coast much lower fitness (no insecticide) • Ester+4 less protection from mosquitoes at coast, but more common than Ester1.. Higher fitness inland because less cost of predation. BUT higher costs due to overproduction of esterases. • Antagonistic Pleiotropy Pesticide resistance and pleiotropy

Genetic drift: will always lead to higher fitness of individuals in the population reduces genetic variation within a population can lead to divergence between populations b and c are correct a, b, and c are correct. b and c are correct . Inbreeding results in a higher frequency of _____ in a population. Inbreeding depression occurs because _____. deleterious alleles; individuals with deleterious alleles have high mortality heterozygosity; heterozygotes have lower fitness homozygosity ...
Alleles are selectively neutral if they have no effect on the fitness of their bearers. This phenomenon often occurs when genetic variation at a locus does not effect the phenotype of an individual. Selection acts on whole phenotypes of individuals.

Finite population sizes lead to genetic drift, which is widely recognized as a major evolutionary force by itself. The presence of genetic drift invalidates the stability of the allele frequencies (postulate 2). On the other hand, genetic drift only affects allele frequencies from one generation to the next and is therefore not visible when looking at a single generation. As a result, genetic drift does not affect the expected genotype frequencies (postulate 1). However, population size does ...

In a population of infinite size, which statement accurately describes the eventual fate of a new beneficial allele? (a) If it is dominant, it will reach fixation; if it is recessive it will rise to high frequency but not reach fixation (b) If it is ...
Genetic drift can rapidly homogenize allele frequencies in different populations. If unchecked by other processes, genetic drift will result in a genetically uniform population. Genetic drift changes only genotype frequencies, not allele frequencies. The effective population size is usually larger than the actual population size.

Genetic drift means random changes in gene frequency from generation to generation, unrelated to any consistent difference in fitness. Using statistics, we can see that it becomes more important the smaller the population is, especially if there are big, but random differences in the reproductive success of different individuals in it
