Determine which of the following characteristics are environmental, not inherited.
II. Blood group.
III. Language spoken.
IV. Eye color.
Inherited characters are those which are produced by the genotype of the organism. They cannot be changed or acquired over time. However, some characteristics are also caused by the environmental effect on the organism. They can be altered by changing the environment around the individual.
Answer and Explanation:
Option I) weight and III) language spoken are characteristics that are environmental.
They are those characteristics which an individual acquired overtime and can be altered by changing the environment. Weight of the individual depends upon the metabolism of the individual and it cannot be inherited from the parents. Language spoken is also an environmental trait as it is learned from the people around us and not encoded in our genes.
On the other hand, blood group and eye color depends on the parents as they are inherited traits and cannot be altered no matter what.
