How does your DNA affect you?
GENES AND TRAITS
Your genotypic pattern sets you apart from other people. Genes are responsible for the entire make-up of your body. Your physical appearance (phenotype) is the result of the combination of genes that you inherit from your parents (genotype). From your eye color, the shape of your face, cleft in your chin, size of your nose, curl in your hair to your behavioural patterns, you probably share a number of characteristics with your parents. Although you share some of these similarities you differ from them and other people owing to the small variations in your genetic makeup. In addition to these variations that influence your individual characteristics some of these gene variants may impact your health condition and are termed as “polymorphisms”. The human genome sequence is 99.6% identical in all people.
