The Good, the Bad, and the Ugly

Conservation Genetics is in the good, the bad, and the ugly spotlight. Conservation Genetics “aims to understand the dynamics of genes in populations principally to avoid extinction.” Clear as mud? An Example It may be easier to understand with an example. Conservation genetics aims to help endangered species, like African cheetahs. Today the existing 10,000 African cheetahs share 99 percent of their DNA. In other words, they’re all related. This means there is little genetic diversity. Low genetic diversity leads to a population that is highly susceptible to disease. Disease that could make the African cheetahs extinct. Scientists involved with cheetah breeding projects determine how closely related two cheetahs are. They want to reintroduce genetic variety into the population of cheetahs. So, they choose the ones that are the furthest apart genetically and breed those two together.  If they are successful, the cheetah population will grow.

Its mission is to “enhance biodiversity through new techniques of genetic rescue for endangered and extinct species.” One of their funded projects searches for the genomic trigger of bleaching the coral reefs. They say that this study has the “potential opportunity to […]
