(i) Differentiate between dominant and recessive traits.
(ii) 'Gene control traits'? Explain this statement with an example.

Explanation

(i) (a) The character which gets expressed in the presence of its contrasting form is termed as dominant trait.
(b) The trait which remains unexpressed in the presence of its contrasting form is called recessive trait.
(ii) Consider tallness as a characteristic. Plant height depends upon particular plant hormone which in turn will depend on the efficiency of the process for making it. If the enzyme responsible for the production of this hormone is efficient, plant will be tall. If the gene for that enzyme has an alteration that makes enzyme less efficient, the amount of hormone will be less and plant will be short.
