The ratio of maternal DNA to the paternal DNA in the offspring is _____.
A
Correct answer
Explanation
In sexual reproduction, each parent contributes exactly half of the offspring's genetic material. A human offspring receives 23 chromosomes from the mother and 23 chromosomes from the father, creating a total of 46 chromosomes. This means the ratio of maternal DNA to paternal DNA is exactly 1:1. Neither parent contributes more genetic material than the other.
