8. Role of heredity
Heredity is defined as the way in which
characteristics and physical features passed on from
parents to their baby (Sincero ,2013). Physical
features such as hair color, eye color, weight and
height are called traits. These traits contain genetic
information which is stored in genes. “These genes
are found in strands of DNA referred to as
chromosomes” (Sincero ,2013, p.2). Genetics can
influence on people’s behavior as well. Also, there
are genetically inherited diseases such as downs
drome.
