which of the following is true of most human traits?
a they are influenced by a single gene.
b they may be influenced by different genes interacting with your specific environment.
c they are directly related to your individual environment.
d they are influenced by a specific group of genes only.

Explanation:

Most human traits are polygenic (influenced by multiple genes) and also affected by environmental factors. This is known as gene - environment interaction. Option A is incorrect as few traits are influenced by a single gene. Option C is wrong because traits are not just directly related to the environment without genetic influence. Option D is incorrect since traits are not only influenced by genes but also by the environment. Option B correctly states that human traits may be influenced by different genes interacting with the specific environment.

Answer:

B. They may be influenced by different genes interacting with your specific environment.
