Q.
Multiple alleles are present
AIPMTAIPMT 2015Principles of Inheritance and Variation
Solution:
Multiple alleles refer to the presence of more than two alternate forms of a gene which should be accommodated on two loci on a homologous pair. This is facilitated by the presence of more than one allele on the same locus of a chromosome provided one allele is present at a locus at a time.
