Question

Multiple alleles are characterised by

• A. More than two alternate forms of a gene found at same locus
• B. More than two alternate forms of a gene found at different loci
• C. Occurrence of one gene in two chromosomes
• D. None of the above

Answer 1

The correct option is A More than two alternate forms of a gene found at same locus

More than two alternative forms of a gene in a population occupying the same locus on a chromosome or its homologue are known as multiple alleles. These alleles may show codominance, dominance-recessive behavior, incomplete dominance among themselves. They confirm to the Mendelian pattern of Inheritance.

So, the correct option is ‘More than two alternatie forms of a gene found at the same locus’.
