Question

Difficulty: MediumGenetics and Heredity

Match each foundational genetic term on the left with its corresponding biological definition on the right.

  • GenotypeThe specific genetic makeup or combination of alleles possessed by an organism
  • PhenotypeThe observable physical or biochemical characteristics of an organism
  • AlleleAn alternative or variant form of a single gene located at a specific locus
  • ChromosomeA condensed structure of DNA and histone proteins carrying hereditary information

Answer

Genotype matches the specific genetic makeup or combination of alleles; Phenotype matches the observable physical or biochemical characteristics; Allele matches an alternative or variant form of a single gene; Chromosome matches a condensed structure of DNA and histone proteins.
Each term is accurately matched to its precise biological definition: Genotype is the organism's allele combination, Phenotype is the observable physical trait, Allele is a specific variant form of a gene, and Chromosome is the organized thread-like structure of DNA and protein.

Step-by-Step Solution

1
Differentiate between genetic code and physical expression.
Genotype corresponds to the underlying genetic makeup and allele combination, whereas phenotype represents the observable physical traits.
Genotype is the internal genetic instructions, while phenotype is the outward result.
2
Distinguish between individual gene variations and macroscopic cellular structures.
An allele is an individual variant of a gene, whereas a chromosome is the large organized package composed of DNA and proteins containing many genes.
An allele is a sub-unit of genetic sequence variation, while a chromosome is the structural vehicle for genomic DNA.
3
Pair each genetic term with its exact corresponding definition.
All four pairs are accurately aligned based on precise biological terminology.
Each definition uniquely identifies the specific level of genetic organization and function.
