Mountain Lion Kittens Discovered To Be Product Of Inbreeding
2012-08-03 16:52:18

Brett Smith for redOrbit.com - Your Universe Online In what should have been a happy occasion, the celebration of twin mountain lions´ birth, officials with the National Park Service were tempered by the discovery that two kittens -- a male and female -- are the second documented case of inbreeding at the Santa Monica Mountains National Recreation Area. According to officials, the two kittens, called Puma 23 and 24, are likely the product of a father lion that mated with his female...

Promiscuous Queen Bees Maintain Genetic Diversity

[ Watch the Video ] By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy. The results, published in the current issue of PLoS ONE, focused on giant honey bee colonies on Hainan Island, off the coast of China. Since these bees have long been separated from their continental cousins, it was thought that the island bees would be prime candidates for inbreeding as well as having very different genes, said Zachary Huang, Michigan State...

TAU breeds population of lab mice with genetic diversity closer to humans With a 95 percent genomic similarity to humans, mice have long been used to learn about the genetic causes of human disease. Once researchers can shine a light on the genetic factors that cause disease in mice, they can start to develop prevention and treatment options to protect the human population. But this process, called genetic mapping, is a long and difficult road, made more challenging by the 5% difference...

For a bigger harvest and faster results: The University of Hohenheim, the MPI for Molecular Plant Physiology and the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben start a new chapter in plant breeding In order to breed new varieties of corn with a higher yield faster than ever before, researchers at the University of Hohenheim in Stuttgart, Germany, and other institutions are relying on a trick: early selection of the most promising parent plants based on their...

A new National Oceanographic and Atmospheric Administration (NOAA) study has raised concerns that killer whales in the Puget Sound could be facing a loss of genetic diversity due to inbreeding. The NOAA study, which was published online this month in the Journal of Heredity, followed the Washington-based whale species and studied their mating habits. They discovered that some of the offspring had been produced as a result of matings within the same pod or social subgroup, the researchers said...

New research has found that in urban fox families, the mothers are the ones who decide which cubs stay and which must leave. Red foxes have successfully established themselves in urban areas, living in family groups with a dominant male-female pair and a varying number of subordinate adults, according to the researchers. Some of the cubs remain in the family group for the rest of their lives, while others leave to search for another family to join. Scientists have hypothesized what drives...

A research team led by Teh-hui Kao, professor of biochemistry and molecular biology at Penn State University, in collaboration with a team lead by Professor Seiji Takayama at the Nara Institute of Science and Technology in Japan, has discovered a large suite of genes in the petunia plant that acts to prevent it from breeding with itself or with its close relatives, and to promote breeding with unrelated individuals. In much the same way that human inbreeding sometimes results in genetic...

Fewer males than females are surviving the negative effects of inbreeding in a reintroduced population of a rare New Zealand bird, reports new research published in Proceedings of the Royal Society B. Studying a population of the endangered New Zealand Hihi, researchers from the Zoological Society of London found that male survival rate was 24 per cent lower than their female siblings during early development, and as chicks. The researchers analysed 98 clutches on Tiritiri Matangi Island, a...

Inbred male sperm have been found to fertilize fewer eggs when in competition with non-inbred males according to a new study by the University of East Anglia. Research into the breeding habits of the red flour beetle, published June 15 in Proceedings of the Royal Society B, shows that the reduced fitness of inbred beetles, known as 'inbreeding depression', reveals itself in competitive scenarios. Inbreeding is a potentially important problem in declining species across the world, and...

New research suggests that Charles Darwin's family was a living human example of a theory that he developed about plants: that inbreeding could negatively affect the health and number of resulting offspring. Darwin was married to his first cousin, Emma Wedgwood. They had 10 children, but three died before age 10, two from infectious diseases. And three of the six surviving children with long-term marriages did not produce any offspring "“ a "suspicious" sign, researchers say, that these...
