The estimates of effective population size based on linkage disequilibrium are virtually unaffected by natural selection.

PLoS Genetics, 2022
The effective population size (Ne) is a key parameter to quantify the magnitude of genetic drift and inbreeding, with important implications in human evolution.

A polygenic basis for birth weight in a wild population of red deer (Cervus elaphus)

G3: Genes, Genomes, Genetics, 2023
The genetic architecture of traits under selection has important consequences for the response to selection and potentially for population viability. Early QTL mapping studies in wild populations have reported loci with large effect on trait variation ...

The Evolutionary Consequences of Selection at the Haploid Gametic Stage [PDF]

The American Naturalist, 2018
As an immediate consequence of sexual reproduction, biphasic life cycles with alternating diploid and haploid phases are a common characteristic of sexually reproducing eukaryotes. Much of our focus in evolutionary biology has been directed toward dynamics in diploid or haploid populations, but we rarely consider selection occurring during both phases ...

Assessing by Modeling the Consequences of Increased Recombination in Recurrent Selection of Oryza sativa and Brassica rapa

G3: Genes, Genomes, Genetics, 2019
Meiotic recombination generates genetic diversity but in most species the number of crossovers per meiosis is limited. Previous modeling studies showed that increasing recombination can enhance response to selection.

Genomic consequences and selection efficacy in sympatric sexual versus asexual kelps

Frontiers in Marine Science, 2022
Genetic diversity can influence resilience and adaptative capacity of organisms to environmental change. Genetic diversity within populations is largely structured by reproduction, with the prevalence of asexual versus sexual reproduction often ...

On the Evolutionary Consequences of Disruptive Selection [PDF]

Bolletino di zoologia, 1973
Abstract Allo scopo di analizzare le conseguenze evolutive della selezione divergente sono state considerate quattro linee di Drosophila melanogaster ottenute sia mediante selezione direttiva (HH, LL) sia mediante selezione divergente (HL, LH) per la lunghezza dell'ala.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Sexual selection and genotype-by-environment interactions in Drosophila cuticular hydrocarbons

, 2014
Cuticular hydrocarbons (CHCs) have important functions in insects, including waterproofing, species recognition, and signaling. They can act as pheromones and facilitate chemical mimicry, can be relatively simple or complex, and they have been the ...

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Immune response from a resource allocation perspective

Frontiers in Genetics, 2012
The immune system is a life history trait that can be expected to trade off against other life history traits. Whether or not a trait is considered to be a life history trait has consequences for the expectation on how it responds to natural selection ...
