Effectiveness of managed gene flow in reducing genetic divergence associated with captive breeding

open access: yesEvolutionary Applications, 2015
Captive breeding has the potential to rebuild depressed populations. However, associated genetic changes may decrease restoration success and negatively affect the adaptive potential of the entire population.

pixy: Unbiased estimation of nucleotide diversity and divergence in the presence of missing data

open access: yesbioRxiv, 2020
Population genetic analyses often use summary statistics to describe patterns of genetic variation and provide insight into evolutionary processes. Among the most fundamental of these summary statistics are π and dXY, which are used to describe genetic ...

Isolation, marine transgression and translocation of the bare‐nosed wombat (Vombatus ursinus)

open access: yesEvolutionary Applications, 2019
Island populations can represent genetically distinct and evolutionarily important lineages relative to mainland conspecifics. However, phenotypic divergence of island populations does not necessarily reflect genetic divergence, particularly for lineages

Floral and genetic divergence across environmental gradients is moderated by inter-population gene flow in Platanthera dilatata (Orchidaceae)

open access: yesFrontiers in Ecology and Evolution, 2023
Understanding how natural selection acts on intraspecific variation to bring about phenotypic divergence is critical to understanding processes of evolutionary diversification.

Estimating genetic divergence and genetic variability with restriction endonucleases. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1981
Restriction endonucleases cut DNA at specific sites determined by the local nucleotide sequence. By comparing related DNA segments with respect to where such cuts are made, one can estimate the extent of sequence homology between the segments. Empirical methods are presented here for using these data to measure the proportion of mismatches between two ...

Rapid genetic divergence in response to 15 years of simulated climate change

open access: yesGlobal Change Biology, 2015
Genetic diversity may play an important role in allowing individual species to resist climate change, by permitting evolutionary responses. Our understanding of the potential for such responses to climate change remains limited, and very few experimental

Common garden experiment reveals genetic control of phenotypic divergence between swamp sparrow subspecies that lack divergence in neutral genotypes. [PDF]

open access: yesPLoS ONE, 2010
Adaptive divergence between populations in the face of strong selection on key traits can lead to morphological divergence between populations without concomitant divergence in neutral DNA.

Genetic divergence in mung bean [PDF]

open access: yesLEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2017
The present study was undertaken to provide information on the nature and magnitude of genetic diversity among 30 mung bean genotypes for yield traits by using Mahalanobis’s D2 statistics. Thirty genotypes could be grouped in 6 clusters, cluster VI showed maximum intra-cluster distance while the highest inter-cluster distance was observed between ...

Heterotic hybrid frequency in relation to combining ability and parental genetic divergence in maize

open access: yesElectronic Journal of Plant Breeding, 2018
Being a highly cross pollinated crop, heterotic hybrid development is the immediate cultivar option in maize. The F1’s developed from the heterotic pools not only serve as hybrid cultivar but also helps in isolation of good inbred lines.

Genetic divergence for adaptability and stability in sugarcane: Proposal for a more accurate evaluation.

open access: yesPLoS ONE, 2021
The best agro-industrial performance presented by a crop genotype in one environment may not be reproduced in another owing to complex edaphoclimatic variations.
