Heterosis and hybrid crop breeding: a multidisciplinary review
Although hybrid crop varieties are among the most popular agricultural innovations, the
rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower …

Adaptive introgression in animals: examples and comparison to new mutation and standing variation as sources of adaptive variation
PW Hedrick - Molecular ecology, 2013 - Wiley Online Library
Adaptive genetic variation has been thought to originate primarily from either new mutation
or standing variation. Another potential source of adaptive variation is adaptive variants from …

Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation
Genetic rescue–ameliorating inbreeding depression and restoring genetic diversity of inbred
populations through gene flow-is valuable in wildlife conservation. Empirically validated …

Y recombination arrest and degeneration in the absence of sexual dimorphism
T Lenormand, D Roze - Science, 2022 - science.org
Current theory proposes that degenerated sex chromosomes—such as the mammalian Y—
evolve through three steps:(i) recombination arrest, linking male-beneficial alleles to the Y …

Distance from sub-Saharan Africa predicts mutational load in diverse human genomes
The Out-of-Africa (OOA) dispersal∼ 50,000 y ago is characterized by a series of founder
events as modern humans expanded into multiple continents. Population genetics theory …

Incomplete dominance of deleterious alleles contributes substantially to trait variation and heterosis in maize
Deleterious alleles have long been proposed to play an important role in patterning
phenotypic variation and are central to commonly held ideas explaining the hybrid vigor …

Mutation load: the fitness of individuals in populations where deleterious alleles are abundant
Many multicellular eukaryotes have reasonably high per-generation mutation rates.
Consequently, most populations harbor an abundance of segregating deleterious alleles …
