Genetic diversity

Levels of biodiversity. 3 scales: a.) ecosystem diversity is the variety of ecosystems within a region. b.) species diversity is the variety of species within an ecosystem c.) genetic diversity is the variety of genes among individuals of a species.

As it says in the Nina Simone song: “It’s a new dawn, it’s a new day… and I’m feeling good.” This morning, we awoke to a country where the Democrats will control the House of Representatives — a major step forward for the whole checks and balances thing. It’s a morning where our new House […]

Lack of regulation and debate over the merits of genetic testing for diseases has lead some insurance companies to avoid funding the technology. Illustration by Getty Images The day when a simple blood test or saliva sample can identify your risk for medical conditions ranging from cancer to Alzheimer's disease seems tantalizingly close. But while advances in genetic testing increasingly give people critical information that may help prevent disease, genetics experts say sometimes the hype

Human population density and land use is causing changes in animal genetic diversity, according to researchers at McGill University. The loss of genetic diversity will hinder the ability of plant and animal populations to adapt to changing environments [Credit: McGill University] The findings reported in the journal Ecology Letters, show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The…

There are three types of biodiversity they are as follows: genetic, species and ecosystem. All three interact and change over time and from place to place.

Domesticated crop plants tend to have low genetic diversity because they have usually been selectively bred from varieties that are genetically related. This cross-breeding approach produces high-yield varieties, but it can also increase susceptibility to disease and pests.[1] Cross-breeding these…
