A breed of guinea pig has a gene that causes yellow or brown hair. The combination of alleles that an individual has for this gene is called the _________, and yellow and brown states are called _____________.

Question

The question asks about the genetic terminology used to describe an individual’s gene variants and their observable traits in a guinea pig species.
Option 1: 'genotype; phenotypes' correctly pairs the terms. The combination of alleles for a gene is called the genotype, and the observable trait states (yellow or brown hair) are the phenotypes. This aligns with standard genetic language.
Option 2: 'haploid; diploid' describes the number of chromosome sets, not the combination of alleles for a single gene or the observable trait states. A guinea pig typically has diploid cells, but this option mislabels the concept at hand.
Option 3: 'heterozygous; homozygous' refer to the relationship between two alleles at a locus (whether they are different or the same). While these terms describe specific genotypic states, they do not name the overall combination of alleles (genotype) or the observable traits (phenotypes) themselves.
Option 4: 'phenotype; genotypes' reverses the standard order. Phenotype is the observable trait, while genotype is the genetic combination; listing them in this reversed order confuses the hierarchical relationship between genotype and phenotype.
Option 5: 'gametes; zygotes' are terms used to describe reproductive cells and the fertilized product, respectively. They do not describe the allele combination at a locus for an individual or its trait expression.
In summary, the correct conceptual pair focuses on the genetic makeup (genotype) and the observable trait expression (phenotypes), while the other options either mix up, misuse, or reverse these fundamental genetic ideas.
