Where are the choices?
the answer could be that both parents are carrying the heterozygous genes. so let's say B is the dominant brown eye gene and b is the recessive blue eye gene. both parents could possess the Bb genotype, and hence by using test cross, Tim was that 25% chance where a child could inherit the bb genotype to have blue eyes

Explanation:
DNA is present as the genetic material of the living organism. Hershey and Chase experiments confirmed that only DNA is transmitted from one generation to the next generation.
They used radioactive phosphorus and sulfur and infects the cells with bacteriophage. The radioactivity labelled with phosphorus is present in the next generation whereas the radioactive sulfur molecules are not present in the next generation. DNA contains phosphorus whereas sulfur is present in the proteins.
Thus, the correct answer is option (D).
