Genetics – a branch of biology that deals with the study of heredity and variations Variations – differences amongst the individuals of the same species and the offspring of the same parents. Variations can be due to mutations. Gene is the functional unit of heredity. Heredity includes those traits or characteristics which are transmitted from..

FAAH-OUT mutation for a life of no pain – No FAAH, no pain
A Scottish woman claims that she has not experienced pain over some supposedly painful conditions, like a severe joint degeneration or a post-operation she underwent for her hand due to osteoarthritis.

Mitochondrial DNA not just from moms but also from dads?
If one wants to trace down lineage, that person could turn to the cell’s powerhouse, the mitochondrion. This organelle contains its own special set of DNA believed as inherited solely from mothers across generations. Thus, looking at the mitochondrial DNA (by mtDNA genealogical DNA testing) could help track down lineage, and for this reason, help..
SELFISH GENE – selfish to persist
What is a selfish gene? A selfish gene is not a gene that makes an individual selfish. In fact, it may even be involved in the demonstration of a selfless act, a mark of altruism. Selfish gene elements (or selfish DNA) are nucleotide sequences that make copies of itself within the genome. They are regarded..
Men could go extinct? Y chromosome disappearing slowly
Hold on to your seats, gentlemen — the male chromosome (Y chromosome) disappearing at a certain rate could absolutely be gone in the future. This presumption is based on genetic studies. It used to be genetically the same as the X chromosome. However, it has degenerated gradually, and now, it shriveled and became less relevant…
