Researchers now confirm that genome duplication drives evolution of species

Many wild and cultivated plants arise through the combination of two different species. The genome of these so-called polyploid species often consists of a quadruple set of chromosomes - a double set for each parental species - and thus has about twice as many genes as the original species.

Genetic testing can play a substantial role in medical management

Genetic testing can play a substantial role in medical management by uncovering changes in genes that are associated with an increased risk for hereditary cancers.

	NIH-funded genome centers to speed up breakthroughs in precision medicine The All of Us Research Program awarded funds totaling $28.6 million to establish three genome centers around the country. These centers will begin to generate genomic data from biosamples contributed by the program's participants.

	Study explores link between genetic predisposition to Alzheimer's and cardiometabolic risk factors Alzheimer's disease is the most common memory disorder. In addition to genetic predisposition, the risk of Alzheimer's disease is also increased by cardiometabolic risk factors, such as type 2 diabetes. The accumulation of these risk factors is known as the metabolic syndrome.

	Environmentally-induced gene activity influences IQ test performance Is there a link between differences in IQ test performance and the activity of certain genes? Researchers from Charité - Universitätsmedizin Berlin have shown that modifications in the structure of a specific gene have a negative impact on individual test performance.

	Genes predicting person's height may provide clues about causes of varicose veins A person's height and certain genes that predict height are associated with varicose veins and may provide clues about what causes this condition and ways to prevent and treat it, according to new research in the American Heart Association's journal Circulation.
