Solution
Gr
Explanation:
A normal gamete carries only one allele of each gene because gametes are haploid cells formed through meiosis. They contain a single set of chromosomes, so they cannot have pairs of alleles, only one allele per gene locus. Hence, genotypes like Gg or Rr (heterozygous) cannot be gametes; only single alleles like G or r appear in gametes.
