Blue-eyed parents may have green-eyed babies. Every physical, emotional, mental and health trait exhibited by an individual is all due to gene expression. Dominant traits require only one copy of a dominant gene to outwardly express that trait. Genes store the information needed for the cell to assemble proteins, which eventually yield specifi c physical traits. But what other things came from our predecessors? A single gene determines several traits and certain traits are determined by few genes. genetics: The branch of biology that deals with the transmission and variation of inherited characteristics, particularly chromosomes and DNA. Scientists have known for years that traits such as eye color and hair color are determined by specific genes encoded in each human cell.The nature theory takes things a step further by suggesting that abstract traits such as intelligence, personality, aggression, and sexual orientation can also be encoded in an individual's DNA.

This family activity can help your child learn to identify inherit-ed traits. In a study published today in the journal Nature Genetics, the scientists mined existing data from genetic studies and used novel statistical techniques to obtain estimates of the numbers of DNA variations that contribute to different physical traits and diseases, Inherited traits are coded in our DNA and hence can be passed on to the next generation. The main difference between genetic and physical mapping is that the distances of genetic maps depend on the genetic linkage information, but physical maps are based on the actual physical distances as measured by the number of base pairs. In actuality, these Mongoloid-like traits do not occur at a higher average rate than they would in other Northern European groups. Breed trait: Lap and foot warmers.
