Question

Assertion : Both male and femlae parent helps to determine the trait of the progeny

Reason : Male parent contributes two alleles of the gene to control the trait.

• A. A and R both are true
• B. A is false, R is true
• C. A and R both are false
• D. A is true, R is False

Answer 1

The correct option is D

A is true, R is False

A trait is expressed in the body by virtue of two alleles which control the trait. These alleles are present on homologous chromosome pair. One of the homologous chromosomes comes from father and the other one from mother and get restored in the zygote. Thus, both parents contribute equally to the expression of a particular trait in the body of an organism.
