Question

A trait in an organism is influenced by

• A. Paternal DNA only
• B. Maternal DNA only
• C. Both Maternal and Paternal DNA
• D. Neither by paternal nor maternal DNA

Answer 1

The correct option is C

Both Maternal and Paternal DNA

The correct option is C.

Explanation of the correct option:-

1. The term "traits" describes an organism's innate qualities that are passed down from one generation to the next.
2. Genes, which are units of inheritance, carry these features. DNA serves as the genetic building block of genes. The genetic material for a child is equally contributed by both parents.

Explanation of the incorrect options:-

Option A: -

1. An individual's paternal ancestry is investigated through paternal DNA testing.
2. In simple terms, parental DNA testing establishes a child's paternity. The Y chromosome DNA is examined during paternal DNA testing.

Option B: -

The DNA found in mitochondria, which are cellular organelles found in eukaryotic cells that transform chemical energy from food into a form that cells can utilise, such as adenosine triphosphate, is known as mitochondrial DNA (mtDNA or mDNA) (ATP).

Final Answer: - A trait in an organism is influenced by both Maternal and Paternal DNA.
