Research has revealed that a genetic variation protects against type 2 diabetes when inherited from a person's father, but increases risk of the same condition when it comes from the mother. It is among five DNA variants with different medical effects that depend on the parent of origin which have been identified by researchers at deCODE Genetics in Iceland... While hundreds of common genetic variations that affect disease risk have been discovered in the past two years, they together explain only a small fraction of the heritable factors that are known to play a part in conditions such as diabetes, heart disease and many cancers. At least some of this "missing heritability" could be accounted for by genes that vary in their effects with parental origin, which scientists have previously been unable to examine... The research also suggests that the significance of many genetic variations for disease may have been missed by previous studies. Several genes that differ in their effects when inherited from mothers and fathers are already known to science because of a phenomenon called imprinting that can alter the way in which DNA is switched on and off... The best-known example is a defect on chromosome 15, which causes Prader-Willi syndrome if inherited from the father and Angelman syndrome if inherited from the mother: while each condition has different symptoms, both cause severe mental retardation but are rare.

Okay. Now tell us why that is and how that evolved from amino acids? **taps foot**
thanks, bfl
See why I prefer meteors and comets just bringing this stuff in and dropping it in the ocean.
No fear of being burned at the stake for one thing!
Genetic expression. Pardon me while I self-ping.
The article link doesn’t work. But research into Turner’s Syndrome (only one X, no Y) shows an interesting link between which parent a child gets an X from and their behavior. Women born with Turner’s Syndrome who get their X from their mothers behave in a more masculine way while women with Turner’s Syndrome who get their X from their father behave in more feminine ways. This makes sense since boys get their one X from their mothers and girls get their second X from their fathers.
Dunno, the link works fine here. Sometimes UK pages time out during loading though.
Around here there is.
