Sex chromosome genes influence aggression

It has been well documented that, across human cultures and in most mammals, males are usually more aggressive and less nurturing than females.

Father-daughter inbreeding avoidance in a wild primate population

A 14 year behavioral and genetic study of a population of wild capuchin monkeys has shown that fathers almost never mate with their daughters, even though alpha males sire the majority of offspring produced by females unrelated to them.

Mutant genes trigger AMD but may lighten the way to new treatments

According to new research in the U.S., the most common form of blindness in the elderly, age-related macular degeneration (AMD), can be attributed to just two genes which trigger the condition.

As children transform into adults some of the genes involved in controlling their blood pressure change as well

The study of black and white identical and fraternal twins showed that changes in gene expression between ages 14 and 18 accounted for up to one third of the blood pressure variation that occurred by age 18, says Dr. Harold Snieder, genetic epidemiologist at the Medical College of Georgia.

Factor B and H genes found to play role in the development of age-related macular degeneration

A new study, led by researchers at Columbia University Medical Center, pinpoints the role that two genes - Factor H and Factor B - play in the development of nearly three out of four cases of age-related macular degeneration (AMD), a devastating eye disease that affects more than 10 million people in the United States.
