An organism's underlying combination of alleles is its:
AGenotype
BPhenotype
CKaryotype
DPrototype
Answer & Solution
Correct answer: A. Genotype
1. Two different words separate what an organism carries from what it shows.
2. An organism's underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.
3. The phenotype is the visible result of that makeup.
4. Mendel's hybridisation experiments demonstrate the difference between the two.
