QQuestion
The Guinea pig having the genotype BbRr is heterozygous for both the loci.
✓Answer
True.
Explanation:
An organism is said to be heterozygous at a gene locus when it has two different alleles for that gene. The genotype BbRr means the Guinea pig has one dominant allele (B) and one recessive allele (b) for one gene, and one dominant allele (R) and one recessive allele (r) for another gene, making it heterozygous at both loci.
