Choose the correct option regarding the two given statements.

Statement 1: Half of the genetic information in a child comes from father.

Statement 2: Environment does not affect the phenotype (observable characteristics or traits) of a person at all.

• A. Only 1 is correct
• B. Both 1 and 2 are correct
• C. Only 2 is correct
• D. Both 1 and 2 are incorrect

Answer 1

The correct option is A

Only 1 is correct

The first statement is correct as half of the genetic information of any individual comes from either of the parents. But, the second statement is incorrect as environment plays a role in determining the phenotype of the person. Both the genetic and environmental factors together determine the phenotypic expression of a gene in an individual.
