which of the following statements about phenotypes and genotypes is false? a phenotype can be changed by the environment. b genotype affects phenotype by providing the instructions for making proteins. c phenotype is an organisms visible characteristics. d an organisms phenotype is only made up of genes and alleles.

Answer

Brief Explanations:

  • Option A: Environmental factors can indeed modify phenotypes, like how sunlight affects plant color.
  • Option B: Genotypes code for proteins which influence phenotypes.
  • Option C: Phenotypes are observable traits of an organism.
  • Option D: An organism's phenotype is a combination of its genetic makeup (genotype) and environmental - influenced traits, not just genes and alleles. So this statement is false.

Answer:

D. An organism's phenotype is only made up of genes and alleles.
