Traits or distinguishing characteristics are passed from parent to their
children through their gene. The estimated 30,000 gene that make up a human
being are beaded along highly bundled strands of a chemical substance called
deoxyribonucleic acid (DNA).
children through their gene. The estimated 30,000 gene that make up a human
being are beaded along highly bundled strands of a chemical substance called
deoxyribonucleic acid (DNA).
The DNA strands are highly packed into structures called chromosome.
Humans have 46 chromosomes in each cells divided into 23 pairs. Two copies of
chromosome 9, one copy inherited from each parent form one of the pairs.
Chromosome 9 is made up of about 14million DNA building blocks (base pairs) and
represent approximately 4.5 percent of the total DNA in cells. Identifying
genes on each chromosome is an active area of genetic research, because the
researchers use different approach to predict the number of gene chromosome 9
likely contain 800 to 900 genes that provide instructions of making protein.
These proteins perform a variety of different roles in the body. Human females
inherit two copies of every gene on the X chromosome, whereas male inherit only
one, both genes are located in the X chromosome with only a single X chromosome
male who inherit the detective gene (always from their mother) will be unable
to produce the clotting factor and suffer from difficult to control episodes of
bleeding.

Chromosome carry all the genes that determine physical characteristics,
such as height and eye colour, behavioural characteristics such as intelligence
and natural talents, may also be influenced in some way by genes (Yazer, 2006).
