Question

The patterns of phenotypes an individual may develop upon exposure to different environments is called its ________.

1) reaction norm

2) predictability norm

3) variability norm

4) response norm

Answer 1

The patterns of phenotypes an individual may develop upon exposure to different environments is called its reaction norm. The reaction norm refers to the range of phenotypic expressions that can occur in response to environmental influences. So, the correct option is 1) reaction norm.

Step-by-step explanation:

The patterns of phenotypes an individual may develop upon exposure to different environments is called its reaction norm. The reaction norm refers to the range of phenotypic expressions that can occur in response to environmental influences. It reflects how genes and the environment interact to produce different phenotypic outcomes in individuals. For example, a person's height can be influenced by both their genetic makeup and their nutrition, resulting in a wide range of potential heights. So, the correct option is 1) reaction norm.
