Pedigree3
- Assuming unrelated pedigree founders, Pedigree F is the expected proportion of GWIBD given a specific inbreeding constellation. (nature.com)
- Meiotic recombination introduces variation around that expectation (Mendelian noise) and related pedigree founders systematically bias Pedigree F downward. (nature.com)
- Background inbreeding resulting from relatedness between pedigree founders introduces both random noise and bias into the relationship between GWIBD and Pedigree F. If Background F is absent and the relation between fitness and GWIBD is linear, both Pedigree F and GWIBD are error-free predictors in fitness-inbreeding regressions and consequently the regression slopes are unbiased.

Alleles2
- Most founding events involve a reduction in population size, which in turn causes genetic drift effects that can diminish alleles. (guyhowto.com)
- Because males usually have no paired allele to offset the effects of most alleles on the X chromosome, the X chromosome allele is expressed in males even if the trait is recessive. (msdmanuals.com)
Mutation2
- In genetics, a founder mutation is a mutation that appears in the DNA of one or more individuals which are founders of a distinct population. (wikipedia.org)
- Any organism-from a simple virus to something complex like a mammal-whose progeny carry its mutation has the potential to express the founder effect, for instance a goat or a human. (wikipedia.org)
Populations8
- The three smaller founder populations show that one or the other color may predominate (founder effect), due to random sampling of the original population. (wikipedia.org)
- So, these small populations are different from main populations and this is due to these colonizers or founders. (guyhowto.com)
- Mutations and random allele modifications in small populations are collectively called genetic drift, and the founder effect is a piece of genetic drift. (guyhowto.com)
- As a result, populations of founder species are especially sensitive to habitat and ecological modifications, and genetic diseases. (guyhowto.com)
- We can see some interesting examples of this founder effect in human populations. (guyhowto.com)
- The founder effect is a widely known cause of differentiation between populations that span a country mile. (guyhowto.com)
- This is known as the serial founder effect if the specific populations spread over a geographical range do not interbreed. (guyhowto.com)
- In certain populations, the percentage of heterozygotes (carriers) is high because of a founder effect (ie, the group started with few members, one of whom was a carrier) or because carriers have a selective advantage (eg, heterozygosity for sickle cell trait protects against malaria).

Genetics1
- In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. (wikipedia.org)
Genetic drift2
- In addition to founder effects, the new population is often very small, so it shows increased sensitivity to genetic drift, an increase in inbreeding, and relatively low genetic variation. (wikipedia.org)
- The founder effect is a type of genetic drift, occurring when a small group in a population splinters off from the original population and forms a new one. (wikipedia.org)

Generations2
