In a multiple allele system, a gamete possess

The correct option is C 1 allele
In a multiple allele system, a diploid individual contains only two alleles, but in the population multiple alleles for the same gene are present. Individuals possess two alleles for each factor, and their gametes one allele, which is according to the law of segregation. So, in multiple allele systems, a gamete possesses only one allele.
