Why does it take a long time to develop a new variety of tomato?

a. changes in traits happen gradually, over many generations.

b. many plants resist change.

c. tomatoes cannot acquire new traits.

d. a species cannot change over time.

The correct answer is option A

To develop a new variety of tomato there must be some change in the genes of the tomato.

The change in the genes of the tomato can happen by the process of mutation and this happens gradually over many years.

It takes several generations to evolve into a new variety of tomato. The genetic variation in the tomato is the result of mutation that will tend to give rise to a new variety of tomato.

geologic time scale (for gradpoint) =)

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).
