Wild cranberries across North America carry two distinct genetic toolkits shaped by Ice Age climate shifts—and modern ...

Population geneticist Sohini Ramachandran uses computational approaches and develops new techniques to explore human genetic variation and diversity.

Epistasis arises when alleles at one locus modify the phenotypic expression of alleles at another, generating non-additive contributions to trait variation. In natural populations, genetic variance ...

Salicornia is a halophytic flowering plants in the family Amaranthaceae. Here, the authors report chromosome-scale genome assemblies for six Salicornia species and reveal subgenome diversity, species ...

A new ISSR marker study of 93 Moroccan fig cultivars reveals exceptionally high genetic diversity, with 89 percent of ...

Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome ...

When species are subjected to changing environments, they can survive in their current location through genetic adaptation. However, this ability is not unlimited. In a study published in PNAS, ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

A sweeping genomic analysis reveals how psychiatric disorders cluster into five biological families, exposing shared pathways and pinpointing where their genetic roots diverge. Study: Mapping the ...

Genome-wide association studies identify genetic overlap among disorders, providing evidence that their distinctions may be misleading One major difference between psychiatric disorders and purely ...
