A tomato plant with large leaves and round fruits was crossed to a plant with small leaves and oblong fruits.The F₁ consisted of plants with large leaves;about half of these plants made round fruits and the other half made oblong fruits.Two F₁ plants (one with round fruits and one with oblong fruits)were then analyzed through further crossing.The results were:

a)What are the genotypes of the two original parents?
b)What are the expected phenotypic ratios in the progeny of a cross between "F₁ plant #1" and a tester?
c)What gamete genotypes can "F₁ plant #2" produce?
Explain your reasoning behind each of your answers.
