How do genes determine the traits of an organism?

The genes, which are part of DNA, contain the genetic information inherited from the parents determine the traits of an organism.

The ‘complete set of all the genes and the DNA’ is called the genome which stores the entire set of information of how an organism is structured and maintained.

The pattern of dominant and/or recessive traits and the genetic variations are determined by the allelles.  

Explanation:

The genetic codes in the genes represent the particular amino acid codes and their linkages specific to particular protein.  The amino acids link together to form long polypeptide chains of protein molecules.  

These proteins determine various traits through various roles like:

Messenger proteins: Hormones like insulin, estrogen etc., control and coordinate various functions of the body

Pigments: Like melanin determines the color of the hair, skin, eyes.

Structural protein: Like keratin gives structure of hair, nails; myosin determines muscle structure

Antibodies: Determine the immunity of a person

Ion channel proteins, messenger proteins, structural proteins, receptor proteins etc.: Determine various physiological traits.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
