The statement is true: the same phenotype can be produced by more than one genotype. Key points:
- Phenotype is the observable trait, which can result from different underlying genetic configurations due to dominance, epistasis, additive effects, or gene redundancy. For example, a trait like flower color or height can be expressed similarly by multiple allele combinations.
- Different genotypes can yield the same phenotype, especially when one allele masks another (dominance) or when multiple pathways lead to the same phenotypic outcome.
If you’d like, I can give concrete Mendelian examples or walk through specific genotype-phenotype scenarios to illustrate how the same phenotype arises from different genotypes.
