State a difference between a gene and an allele.

1.	State a difference between a gene and an allele.
Answer» Gene : Contains information that is required to express a particular trait /l unit of inheritance // segment of DNA called cistron // sequence of DNA coding for tRNA / rRNA / polypeptide/enzyme. Allele : Genes which code for a pair of contrasting traits / different forms of the same gene / individual gene in a particular gene pair (for same character). Detailed Answer : Gene is a unit of inheritance, specific segment of DNA or a specific sequence of DNA coding for tRNAlr{NA, polypeptide or enzyme that is transferred from the Parent to the offspring. It controls the expression of a character. Allele is an alternative form or forms of a single gene that lie on the same locus of homologous chromosomes. e.g. if a gene controls height then allele is which gives either tallness or dwarfness.
