According to the biological approach, which of the following statements is TRUE?Shade one circle only. A Environment may influence the expression of the genotype. B Genotype is just the expression of the environment. C Outside influences cannot affect the expression of the genotype. D Phenotype is only the expression of the genotype.
Question
According to the biological approach, which of the following statements is TRUE?Shade one circle only. A Environment may influence the expression of the genotype. B Genotype is just the expression of the environment. C Outside influences cannot affect the expression of the genotype. D Phenotype is only the expression of the genotype.
Solution
The correct answer is A: Environment may influence the expression of the genotype.
Here's why:
A) This statement is true according to the biological approach. The biological approach recognizes that while our genes (genotype) provide a blueprint for our bodies and behaviors, the environment can influence how these genes are expressed. This is known as gene-environment interaction.
B) This statement is false. The genotype is not just the expression of the environment. The genotype is the set of genes in our DNA which is responsible for a particular trait.
C) This statement is false. As mentioned in explanation A, outside influences can indeed affect the expression of the genotype. This is a fundamental concept in epigenetics.
D) This statement is false. The phenotype is not only the expression of the genotype. The phenotype is the physical expression, or characteristics, of that trait. It can be influenced by the environment as well as by other genes.
